An experiment is performed to measure the molar heat capacity of a gas at constant pressure using Regnault's method. The gas is initially contained in a cubical reservoir of size 40 cm x 40 cm x 40 cm at 600 kPa at 27C. A part of the gas is brought out, heated to 100C and is passed through a calorimeter at constant pressure. The water equivalent of the calorimeter and its contents is 100 g. The temperature of the calorimeter and its 20C to 30C during the contents increases from experiment and the pressure in the reservoir decreases to Specific capacity heat 525 kPa. of water - 4200 J kgK. Calculate the molar heat capacity Cp from these data. V
