Calculate the heat capacity of a gas sample from the following information: The sample comes to equilibrium in a flask at 25(C and 121.3 kPa. A stopcock is opened briefly, allowing the pressure to drop to 101.3 kPa. With the stopcock closed, the flask warms, returning to 25(C. and the pressure is measured as 104.0 kPa. Determine CP in J mol-1 K-1 assuming the gas to be ideal and the expansion of the gas remaining in the flask to be reversible and adiabatic,
