$A$ sample of $1.0 \ mol$ of a monoatomic ideal gas is taken through a cyclic process of expansion and compression as shown in the figure. What will be the value of $\Delta H$ for the cycle as a whole?

(0) Enthalpy $(H)$ is a state function,which means its value depends only on the initial and final states of the system.
In a cyclic process,the system returns to its initial state after completing the cycle.
Therefore,the change in enthalpy for the entire cycle is zero,i.e.,$\Delta H_{\text{cycle}} = 0$.
