A fixed amount of a gas undergoes a thermodynamic process as shown such that heat interaction along path $B \to C \to A$ is equal to the work done by the gas along path $A \to B \to C$. Then process $A \to B$ is :-
When $1\, kg$ of ice at $0^o C$ melts to water at $0^o C,$ the resulting change in its entropy, taking latent heat of ice to be $80\, cal/gm,$ is ...... $cal/K$
During an adiabatic compression, $830\, J$ of work is done on $2\, moles$ of a diatomic ideal gas to reduce its volume by $50\%$. The change in its temperahture is nearly..... $K$ $(R\, = 8.3\, J\,K^{-1}\, mol^{-1} )$
