MCQ
Assuming that water vapour is an ideal gas, the internal energy change $(\Delta U)$ when $1\, mol$ of water is vapourised at $1\, bar$ pressure and $100\,^oC,$ (given : molar enthalpy of vapourisation of water at $1\, bar$ and $373\, K = 41\, kJ\, mol^{-1}$ and $R = 8.3\, J\, mol^{-1}\, K^{-1}$) will be .............. $\mathrm{kJ\,mol}^{-1}$
- A$41$
- B$4.100$
- C$3.7904$
- ✓$37.904$
