Question
Calculate the heat capacity of a gas sample from the following information: The sample comes to equilibrium in a flask at 25 degree C (298.15 K) 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 degree C (298.15 K), and the pressure is measured as 1040.0 kPa. Determine Cp in J mol-1k-1 assuming the gas to be ideal and the expansion of the gas remaining in the flask to be reversible and adiabatic. Answer: Cp = 56.95J/mol KExplanation / Answer
