For water at \( 100^\circ \text{C} \) and \( 1 \) \( \text{bar} \), \( \Delta_{\text{vap}}H - \Delta_{\text{vap}}U = \) ______ \( \times 10^{2} \) \( \text{J mol}^{-1} \). (Round off to the Nearest Integer)
[Use : \( R = 8.31 \) \( \text{J mol}^{-1} \text{K}^{-1} \)]
[Assume volume of \( \mathrm{H_2O{(l)}} \) is much smaller than volume of \( \mathrm{H_2O{(g)}} \). Assume \( \mathrm{H_2O{(g)}} \) can be treated as an ideal gas]
