The Basics of Boiling Point in Chemistry

The Basics of Boiling Point in ChemistryBoiling point is a measurement of the rate at which water boils. It can be expressed as the amount of heat required to raise the temperature of water to the boiling point. The temperature of water is one of the major considerations in any process involving the use of water.The boiling point of water has been measured in different ways throughout the history of science. In ancient times, it was determined by taking the weight of water in grams per degree Celsius. This method is still in use. Other methods involved taking a number of drops of water from the top of a container and letting them remain in the bottom of another container for some time.The chemical change of water has been described in different ways through time. It is known that at high temperatures, the molecules of water become larger. The molecules of water at these temperatures tend to expand. Because the molecules are moving faster than the speed of sound, the molecules are abl e to escape from the heat of the substance. The faster the molecules are escaping the hotter the substance becomes.Most people are familiar with the measurement of boiling point. However, another important term used in chemistry is the vapor pressure. This is simply the amount of pressure an element exerts on another element at a specific temperature. It is useful in determining the density of substances as they react.A substance with a high pressure is more dense than a substance with a low pressure. These two substances are the basis of all other types of reactions. At its most basic level, the vapor pressure is the amount of force exerted on a fluid by another fluid. Vapor pressure is used for everything from moisture in the air to the temperature of snow and ice on a winter day.Hotness is also measured in terms of the vapor pressure. At very high temperatures, water turns into steam, which can be used as an energy source. Steam, like the vapor pressure, is determined by the dens ity of the substance, the temperature, and the molecular size.The boiling point is also important in combustion. The combustion process takes place when there is a lot of heat energy in a substance. The surface area of the material is a determining factor for the temperature of the substance. Heat energy is transferred from the substance's surface to the substance's interior during combustion.The most important thing to keep in mind about the boiling point is that it is not a direct measure of the temperature of a substance. At any given temperature, the vapor pressure of the substance will be higher than the boiling point. Therefore, boiling point only indicates the temperature of a substance, not how hot it gets. The boiling point of water is useful to help with boiling point measurements and as a basis for other applications.

Scientists who Risked their Lives for Science

Scientists who Risked their Lives for Science Would you risk your life for the sake of science? You might think that scientists only sacrifice a couple hours in the lab or their personal life. However, some scientists do much more, risking their lives in order to contribute to the development of science. Read the shocking stories of 4  incredible scientists: Barry James Marshall In 1984, an Australian Physician Barry James Marshall drank a petri-dish of the Helicobacter pylori bacteria to prove that the bacteria is the cause of most stomach ulcers. Earlier, people thought  that ulcers were caused by stress, spicy foods or too much alcohol. Barry Marshall won  the Nobel Prize in Medicine in 2005. Werner Forssmann In 1929, Werner Forssmann a physician from Germany, demonstrated that a catheter could be advanced safely into the human heart from a peripheral vessel. But could you imagine he did this by advancing a urethral catheter into his own heart! In 1956, Forssmann won the Nobel Prize in Medicine. George M. Stratton In 1897, George Malcolm Stratton an American Psychologists, wore special glasses which inverted images up and down and left and right for over a week. And he discovered that the human brain could adapt to these new conditions. Kevin Warwick In 1998, Kevin Warwick a British Scientist and professor of cybernetics at the University of Reading, UK implanted RFID transmitter beneath his skin, thus becoming the worlds first cyborg: a man-machine hybrid. He could control doors, lights, heaters, and other computer-controlled devices based on his proximity. I hope these true stories will inspire you to study harder, never give up and pursue your dreams.

San Diego College Tutor Transitioning back to college (list)

San Diego College Tutor Transitioning back to college (list) Tips from a San Diego College Tutor: Transitioning back to college (list) Tips from a San Diego College Tutor: Transitioning back to college (list) Wouldn’t it be nice if everyone was able to obtain financial aid, take classes full time and happily maintain a part-time job throughout college and still graduate in four years? This thought will make some people laugh, and others feel just plain angry. It’s getting harder to finish university studies by age 22 these days, but it’s also easier to go back to school after time away from campus. However, there are a few things returning students should consider before they make the leap back to college official. 1 Think about why you stopped attending It’s a good idea for students to think about why they stopped their studies in the first place. The most common issue is money, but there are several other reasons a student may have chosen to leave school. Think about what elements of the original issue are still in play. Is money still an issue? Is that personal or family emergency a thing of the past? Students who go back to school should be aware of what stopped them from graduating the first time around so they can avoid the same issues this time (READ: Going Back to College: A Mature Students Checklist). 2 Do you have support? Returning students may be 23, 33 or 43 meaning they might all be in different stages of life. Support can also mean different things to different people. Maybe the 43-year-old has tuition covered but they may need support from a spouse and children to understand that a lot of their free time will be spent studying. The 33-year-old may need to give up a full-time job (or find an alternative option), and the 23-year-old may struggle to make ends meet while paying hefty tuition fees. Students who have support, be it financial, emotional, or practical are more likely to be successful than students who attempt to undergo this transition completely alone. 3 Will your original degree support your career? Students are encouraged to assess their career goals at this point in their lives. If they originally studied Business Administration, and those last few credits are the only thing standing between them and a big promotion, then their original choice will probably serve them well. On the other hand, if they originally studied Anthropology, but they are now enjoying a successful career as a Real Estate Agent’s assistant, they may choose to pursue a Real Estate license over an Anthropology degree. People’s wants and needs change over time so it’s important to think about where a specific degree may lead you. 4 What educational format works best for you? Returning students may decide they can only go to school part-time or that an online format works best for them at this stage of life. Alternatively, other students will want to go back to the traditional on-campus learning experience. Prior to making another long-term commitment, it’s important for people to think about which educational format will suit their current lifestyle (READ: 5 Tips to Help You Be a Great Student Writer). 5 How many of your credits will transfer to a new university? Many students will not be able to go easily back to their original university, especially if they stopped attending classes several years ago. The best thing to do is obtain transcripts from the original university and meet with an academic counselor at potential new universities. An academic counselor will be able to tell students which credits will transfer and which courses need to be taken over again. A student may discover that one university may require two years worth of repeat courses to obtain a degree while another one may allow a student to graduate in under a year, which can make all the difference to a busy adult student.

College Majors

College Majors Dear high school seniors, when you sit in a cubicle for the next 50 years of your life for nine hours a day, what do you want to do? Think about it, and let yourself know in a few years. The earlier one can declare a major the better. However, it is very important for students not to pigeon-hole themselves into majors before college even starts. Choosing a major is one of the most important decisions students can make, and they need to choose carefully. After all, it very well could be what you do every day for the next 50 years. Carefully choosing a major does not entail typing Economics Jobs into Google or asking all of ones relatives about the different college majors. Students need to see and live their majors before hastily choosing one because its Monday morning and the communications market is supposedly growing. Students should enter college with an idea of what they want for in a career. It is important to have a major; however, when youre 18, trying to figure out which video game you will enjoy more for the next month can be a tough choice. Roughly 50% of college freshmen change their majors, according to MSNBC news.Therefore, freshman year of college is more about deciding a major than building repertoire within ones major. We recommend that freshmen engage in very diverse learning programs, participating in many different extra-curricular activities and classes. Students never know what could spark their interest in a specific major. Therefore, its important for them to keep an open mind. Students should get involved in different clubs and organizations and experience different classes to see what is out there. Who knows, maybe a certain professors chicken scratch on a chalkboard is more interesting to you than another professors. Also, colleges offer a lot of classes that high schools do not. Students should participate in these classes to learn something different. Freshman year is usually the only year in which students can have a broad learning experience. Once students get further along in their college programs, classes will become more specialized. Freshmen students have the rest of their lives to learn everything there is to know about one general field. That is why freshmen should learn a little bit about everything. Your college degree should represent what you love to do and what you do best. Its a decision that should not be taken lightly. Freshman year will help one decide exactly what that degree should be. Also, dont panic if youre done with your freshman year of college, and you do not have a major. There will always be time to find something you love. We encourage you to take that time.

Online Algebra 1 test Tutors

Online Algebra 1 test Tutors This test has been designed to solve various algebraic expressions and algebraic equations. The test involves examples followed by questions of the similar type of practice. We believe these tests would provide adequate practice to the students to solve algebra related problems up to a particular level. Not only this, this tool also provides feedback report as well as after test, it also provides relevant answers to the problems. This can be more understood by taking two test questions and their solution as well. Example 1: If the cost of 20 books is $400, find the cost of 12 such books. Solution: - The cost of 20 books is $400 To find: - We have to find the cost of 12 such books. Let the cost of 1 book be x Cost of 20 books would then be (20) x= 20x (1) But according to the question cost of 20 books is 400 ... (2) Now from the equation (1) and (2), we will get 20x=400 Dividing both sides by 20 20x/20 = 400/20 x= 20, which is the cost of the 1 book Therefore the cost of 12 books = 12(x) = 12 x 20 =$240. Example 2:- Simplify (10x-5x +11) (6x-12x+15) Solution 2:- To simplify the above equation, first of all we need to open the parentheses and then we need to distribute the negative sign in the 2nd parentheses. =10x-5x+11-6x+12x-15 =10x-6x-5x+12x+11-15 = 4x+7x-4. Therefore 4x+7x-4 is the solution and the simplified form of (10x-5x +11) (6x-12x+15).

Connotation and Denotation

Connotation and Denotation Connotation and Denotation Words have duel meaning, a straight forward or literal meaning and a hidden meaning that is connected to the emotions and imagination. In other words they have both denotative and connotative meanings. Denotation is the literal or dictionary meaning of a word and connotation meaning is related to the emotional association that we attach to a word. For example, the word snake has two meanings; the literal meaning is that of a scaly reptile that slithers on the ground. The connotative meaning is different when we refer to the snake we think of evil. Many words carry two meanings, an actual meaning which is known as denotation and an imaginative or emotional meaning, known as connotation. We will understand the concept better if we look at an example of connotation in a sentence and analyze it. Harry is a chicken; he cannot face his enemies face to face. Literal meaning of chicken is a small animal that tastes good, but the implied meaning of chicken is something else here. The connotative meaning of chicken means is somebody who is a coward or is afraid to face danger. Denotation in a sentence Denotation means literal or real meaning of a word that is given in a dictionary. To explain further let us look at a denotation in a sentence and analyze it thoroughly to get the literal meaning of a word. Example: I saw a white dove flying against a blue sky. Literal or actual meaning of the word dove a small bird that is docile and harmless. In this sentence dove refers to the actual bird. Connotation in a sentence Connotative meaning of the word is not so straight forward, it is imaginative, and relates to some idea, concept of emotion. Let us look at the earlier example, a white dove the symbolic meaning of a white dove is peace. So if we apply connotative meaning to the above sentence its meaning changes. The individual saw the emblem of peace in the sky. Connotation and Denotation Denotation is exactly what the dictionary says, many words have similar denotative meaning but their connotative means depends on the context in which they are used. Take the example of the word quest. The literal meaning of quest is in search of something. There are several other meanings of quest, these are hunt,seeking,journey,mission,enterprise. While quest sounds good, hunt that has the same meaning appears to be a little negative. Hunt is generally connected with an aggressive action, and gives negative meaning. Depending on the context a word conveys a negative or positive meaning. Let us look at the way the word hunt and the way it is used in three sentence I am going on a hunt with my friends The police has started a hunt for the perpetrators of the crime Let us hunt together for better opportunities. In the first sentence the word hunt is used in the neutral form, to catch or kill wild animals. The same word takes a negative shade in the second sentence, here it means pursuit in order to punish. The third sentence has more positive vibes, here the word means going on a mission or journey to seek better opportunities. The above example shows that there are three types of connotations, neutral, negative and positive, depending on the feelings associated with the word. Neutral The word neutral means that no feelings, positive or negative, are attached, so a neutral connotation means something that does not engage emotional feelings. Example: Mount Everest is the highest mountain in the world The highest in this sentence is simply stating a fact, there are no feelings, positive or negative are attached to it. Negative and Positive Connotations Negative and positive connotations are related to feelings implied or expressed in a sentence. In other words, negative and positive feelings depend on the context in which the same word is used. The context changes the meaning of the same word. Let us use the same word highest we have used in the neutral sentence. Example: (1) Jim has become a CEO; he has reached the highest pinnacle of his career. (2) Jack deserves the highest punishment for the crime he has committed. The word highest is used to mean the top level in the first sentence to shows positive connotation. The same word highest is used in the second sentence to convey a negative meaning. List of some positive, negative and neutral connotations, generally used in every day language. Positive Connotation Neutral Connotation Negative Connotation Self-confident Arrogant Proud Dignified Snobby Reserved Modest Shy Mousy Venerable Elderly Old
