(chatquestion)...(ii) Irreversible adiabatic expansion : In free expansion, the external pressure is zero, i.e, work done is zero. Accordingly, AE which is equal to w is also zero. If AE is zero, AT should be zero. Thus, in free expansion (adiabatically), AT =0, AE = 0, w = 0 and AH = 0. In intermediate expansion, the volume changes from V, to V, against external pressure, Pext· RT, RT, w = -Pea (V2 - V;) = -Pext %3D P2 P TP-TP2 PP2 =-P xR TP-TP2 PP2 or w = C,(T, -T¡) = -RPext...(Ye kaha se aaya??)
