For water at$100°\mathrm{C}$and$1$bar,
${\Delta }_{vap }\mathrm{H}-{\Delta }_{vap }\mathrm{U}=\underset{¯}{}\times {10}^2 \mathrm{J}{ \mathrm{mol}}^{-1}$
(Round off to the Nearest Integer)
[Use :$\left.\mathrm{R}=8.31 \mathrm{J}{ \mathrm{mol}}^{-1}{ \mathrm{K}}^{-1}\right]$
[Assume volume of${\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)$is much smaller than volume of${\mathrm{H}}_2\mathrm{O}\left(\mathrm{g}\right)$. Assume${\mathrm{H}}_2\mathrm{O}\left(\mathrm{g}\right)$treated as an ideal gas]
