Consider 1.0 mol of an ideal gas that has a molar specific heat capacity at constant volume of 20.8 J K−1 mol−1. Initially, the gas is at a pressure of 4.25 atm and a temperature of 310 K. It is then allowed to expand adiabatically in a reversible manner until the pressure drops to 2.50 atm. Calculate the molar specific heat capacity at constant pressure, the adiabatic constant, the final volume and temperature, and the amount of work done during the expansion.
