Consider a 2-mol sample of an ideal gas, with a molar heat capacity Cv,m = 12.5 J/K-mol, confined to a volume of 5 dm3 at a temperature of 300 K. If this gas sample is heated to 373 K and its volume is allowed to expand to 10 dm3, how much heat (q) is required to perform this process, and what is the entropy change (of the gas) that accompanies this process?
