Vedclass · Answer

(D) The internal energy $U$ of an ideal gas is a state function,which depends only on the temperature of the gas. In a cyclic process,the system returns to its initial state,meaning the final state is the same as the initial state. Since the temperature at the final state is equal to the temperature at the initial state,the change in internal energy $\Delta U$ for any cyclic process is always zero. In all the given figures $(a)$,$(b)$,$(c)$,and $(d)$,the path $A B C D A$ represents a closed loop,which is a cyclic process. Therefore,the change in internal energy $\Delta U$ is zero in all four cases.

In the following figures $(a)$ to $(d)$,the variation of volume with change of pressure is shown. The gas is taken along the path $A B C D A$. The change in internal energy of the gas will be .......
