Consider the following volume-temperature (V−T)(\mathrm{V}-\mathrm{T})(V−T) diagram for the expansion of 5 moles of an ideal monoatomic gas. JEE Advanced 2024 Paper 1 Online Chemistry - Thermodynamics Question 3 English Considering only P−V\mathrm{P}-\mathrm{V}P−V work is involved, the total change in enthalpy (in Joule) for the transformation of state in the sequence X→Y→Z\mathbf{X} \rightarrow \mathbf{Y} \rightarrow \mathbf{Z}X→Y→Z is ‾\underline{\hspace{2cm}}​. [Use the given data: Molar heat capacity of the gas for the given temperature range, CV,m=12 J K−1mol−1\mathrm{C}_{\mathrm{V}, \mathrm{m}}=12 \mathrm{~J} \mathrm{~K}^{-1}\mathrm{mol}^{-1}CV,m​=12 J K−1mol−1 and gas constant, R=8.3 J K−1 mol−1]\left.\mathrm{R}=8.3 \mathrm{~J} \mathrm{~K}^{-1} \mathrm{~mol}^{-1}\right]R=8.3 J K−1 mol−1]
