A system undergoes three quasi-static process sequentially as indicated in Fig. 1-2 is an isobaric process, 2-3 is a polytropic process with gamma = 4//3 and 3-1 is a process in which PV = constant. P_(2) = P_(1) = 4 xx 10^(5) N//m^(2), P_(3) = 1 xx 10^(5) N//m^(2) and V_(1) = 1 m^(3) . The heat transfer for the cycle is Delta Q , the change in internal energy is Delta U and the work done is Delta W . Then
