which can also be written as ∆H=mc∆T + PV. m is the mass of what is being measured in grams. C is the heat capacity which is “the amount of heat energy required to raise the temperature of a body a specified amount” in joules per gram degree Celsius (chemistry.about.com). ∆T is the final temperature minus the initial temperature in degrees Celsius. The amount of work done by the reaction is equal to the pressure of the surroundings multiplied by the volume of the system. P is the pressure of the surrounding

The solute must have a high temperature coefficient in the solvent: it must be soluble at high temperatures and insoluble at low

the capillary tube‚ I recorded the temperature. I then repeated these steps two more times and took the average of the temperatures. The next step was to determine the melting point of acetamide. I crushed the acetamide and filled the capillary tube with 2mm if the powder. I then attached the capillary tube to the thermometer and put it into a beaker that is half filled with water. I then heated the beaker and when the acetamide melted I recorded the temperature. Observations Data Table 1: Experiment

the purity of a mixture using melting point tests. • In order to determine the melting point of a substance whose melting point was higher than 100 degrees Celsius you would use oil or glycerol just to achieve a higher temperature so you can run measurements at those high temperatures. Melting point can be measured very precisely at least for pure compounds. • Adding more crystals in the capillary tube would cause there to be errors in the experiment. If too many crystals were added‚ it would cause
