6. Consider a system at T1, P1,V1 which is composed of one mole of a classical ideal gas for which PV=RT and U=A+BT. Let the system change in four steps. The first step is a very slow compression to P2,V2 at a constant temperature of T1. The second step is a quick compression to T3, P3, V3. The third step is a very slow expansion to P4, V4 at a constant temperature T3. The fourth step is a very quick...
