2.00 mol diatomic perfect gas molecules, for which Cp = 7/2R, is changed from 25°C and 1.50 atm to 135°C and 7.00 atm. Without doing any calculations, is the change in temperature or the change in pressure more important in determining the overall change in entropy (of the system)? Why? What can you conclude about the sign of ΔSsys . Calculate ΔSsys for the change.
