In the two processes shown in the following fi gure, the same amount of heat, q, is supplied to the same gas, gas A. In both processes, the initial temperature and initial number of moles are equal. Process 1 occurs at constant volume; process 2 occurs at constant pressure.

(a) Which gas has the greater fi nal temperature? Explain.

(b) For which process, if any, is it convenient to use the property enthalpy? Explain.
