One mole of an ideal gas in initial state A undergoes a cyclic process ABCA, as shown in the figure. Its pressure at A is P0.Choose the correct option(s) from the following

For n moles of gas with f degrees of freedom at temperature T, we haveU=f2nRTSince, temperature T is same at A and B, soUA=UBAlso, WAB=nRT0loge⁡VfVi=nRT0loge⁡4V0V0        WAB=nRT0loge⁡(4)=P0V0loge⁡(4)
