Consider two identical, finite, isolated systems of constant heat capacity C at temperatures T and T. (T, > T,). An engine works between them until their temperatures become equal. Taking into account that the work performed by the engine will be maximum (=W) if the process is reversible (equivalently, the entropy change of the entire system is zero), the value of Wa (A) CT, T) (C) max is (B) (D) C(T, T,)y2 CyT,-VT) C(T,+T-T,T,)
