Question

Determination of heat capacity of calorimeter of practical

Answer 1

Procedure - A. Determination of the Heat Capacity of the Calorimeter
a) Obtain a 10-mL measuring vessel and measure out 10 mL of cold tap water into the vial of the calorimeter.
b) Monitor the temperature of the water in the calorimeter for several minutes. When the reading appears to be constant, record the temperature.
A simple calorimeter
c) Measure out 10 mL of hot tap water (about 40°C or so) into the 10 mL measuring vessel.
d) Quickly measure the temperature of this hot water then pour the contents of this measuring vessel into the cold water in the calorimeter. Record the temperature of the contents of the calorimeter as soon as possible, and then every 15 seconds for three minutes. Stir constantly during this period.
e)Pour the liquid contents of the calorimeter down the drain, and wipe the glass vial dry with tissue paper.
f)Repeat steps 1 through 5 using the same calorimeter vial as before. Be sure to use this same vial in Part B of the experiment.
