Consider the following volume-temperature (V-T) diagram for the expansion of 5 moles of an ideal monoatomic gas. Considering only $\mathrm{P}-\mathrm{V}$ work is involved, the total change in enthalpy (in Joule) for the transformation of state in the sequence $X \rightarrow Y \rightarrow Z$ is
[Use the given data: Molar heat capacity of the gas for the given temperature range, $C_{\mathrm{V}, \mathrm{m}}=12 \mathrm{JK}^{-1} \mathrm{~mol}^{-1}$ and gas constant, $R=8.3 \mathrm{~J} \mathrm{~K}^{-1} \mathrm{~mol}^{-1} ]$
