The value of C p ​ − C v ​ is 1.00 R for a gas sample in state A and 1.08 R in state B . Let p A ​ , p B ​ denote the pressures and T A ​ , T B ​ the temperatures of states A and B . Most likely:

TestHub · Accepted Answer

The gas behaves more ideally ( C p ​ − C v ​ = R ) at low pressure and high temperature. State B departs more from ideal behaviour, so it has the higher pressure and lower temperature: p A ​ < p B ​ and T A ​ > T B ​ . A.
