Benzoic acid (C6H5COOH) is sometimes used as a standard to determine the heat capacity of a bomb calorimeter.
When 1.44 g C6H5COOH is burned in a calorimeter that is being calibrated, the temperature rises from 19.18 degrees Celsius to 22.93 degrees Celsius. What is the heat capacity of the calorimeter? The heat of combustion of benzoic acid is -26.42 kJ/g.
The temperature change is
deltaT = 22.93 - 19.18 = 3.75 ...
It shows how to calculate the heat capacity of the calorimeter using the combustion of benzoic acid. The solution is detailed and was rated '5/5' by the student who posted the question orginally.
