L AB : HEAT AND THE CALORIE I NTRODUCTION When heat is absorbed by liquid water, the temperature of water rises. The amount of heat necessary to raise the temperature of one gram of water by one degree Centigrade is reasonably constant between 8 o C and 80 o C. Consequently, it provides a simple and reproducible basis for a definition of a standard amount of heat, the calorie. The CALORIE is the amount of heat to raise the temperature of one gram of water one degree centigrade. Conversely, one calorie is released as one gram of water is cooled one degree centigrade. (1 cal= 4.184 J) The purpose of this lab is to use this knowledge of the calorie to determine the heat of combustion per gram of candle wax. You will weigh a candle before you burn it. You will allow water to capture the heat from the burning candle. You will then weigh the candle at the end of the experiment. Calculate the amount of heat gained by the water and divide by the amount of candle wax that was burned to obtain the calories per gram of wax.
