Melting pointe determination #01 Introduction: Objective To learn how to obtain an accurate melting point using a MELTING POINT APPARATUS‚ then use them to draw eutectic curve and determine the eutectic point. Melting point of a solid is the temperature at which the solid and its liquid form are in equilibrium‚ i.e.‚ molecules move back and forth between the two states at the same rate‚ so both phases remain present. If the temperature of a solid is measured carefully as the solid is heated

Pure and impure solids were tested to see what affect pureness/impureness had on a melting point. Background: The melting point of a solid can be used to determine the purity of the solid. Pure samples usually have

Recrystallization and Melting Point of Benzoic Acid Organic Chemistry 1 10/4/12 Abstract Recrystallization was done to remove impurities from the sample. The percent recovery of benzoic acid during recrystallization is 23.02%. The difference between the pure and impure samples was observed by comparison of melting points. It was found that impure sample had a lower and wider melting point range of 120.1-122.2 (C). The pure sample melting point range was 121.3-122.5 (C). These ranges helped determine

Describing Sensor Performance: When describing sensors and instrumentation systems we make use of a range of terms to quantify their characteristics and performance. It is important to have a clear understanding of this terminology‚ so we will look briefly at some of the more important terms. • Range: This defines the maximum and minimum values of the quantity that the sensor or instrument is designed to measure. • Resolution or discrimination: This is the smallest discernible change

America is a Melting Pot America has become a melting pot of ethnic people. If you live in or near a city you can see the many ethnic cultures that influence our lives. America began with waves of immigrants‚ bringing their own cultures and traditions to a new country so they can express them. Nowhere else on this planet can you find such a diverse population. It ’s this mixture that makes America what it is but it also makes up a lot of the problems we face. For centuries the United States

"The Melting Pot Theory" In the 1800’s and the early 1900’s‚ some people gave the America the name‚ the melting pot. People imagined this because thousands and thousands of immigrants coming from around the world were coming into the United States in hope of a better life. So most people imagined that all these different cultures were being poured into a giant pot called America‚ heated to a low boil and molded into one kind of person. If one steps back and thinks about this theory‚ it isn’t
