A perfect gas has a constant volume molar heat capacity of CV,m = 1.5× R, and a constant pressure molar heat capacity of Cp,m = 2.5× R. For the process of heating 4.50 mol of this gas with a 12 W heater for 400 seconds, calculate a) q, w, ?T, and ?U for heating at a constant volume, b) q, w, ?T, and ?H for heating at a constant pressure.
