A thermodynamic system is taken through cyclic process. The total work done in the process is $………\,J$

The specific heat of a gas at constant pressure is more than that of the same gas at constant volume because

In pressure-volume diagram given below, the isochoric, isothermal, and isobaric parts respectively, are

An ideal gas is made to undergo the cyclic process shown in the figure below. Let $\Delta W$ depict the work done, $\Delta U$ be the change in internal energy of the gas and $Q$ be the heat added to the gas. Sign of each of these three quantities for the whole cycle will be (0 refers to no change)

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 :-
