Question

P - V diagram of cyclic process A B C A is as shown in figure. Choose the correct statement, Δ Q A → B is negative, Δ U B → C is positive, Δ W C A B is negative, all of these

A → B , V ↓ , Δ W = - v e As P ↓ , V ⁡ ↓ , so T ↓ So Δ U = - v e Δ Q A → B = negative B → C , P = const., V ∝ T , V ↑ , T ↑ , Δ U = + v e
