What is the internal energy \( (\mathrm{kJ}) \) change occurs when \( 36 \mathrm{~g} \) of \( \mathrm{H}_{2} \mathrm{O}(l) \) converted to \( \mathrm{H}_{2} \mathrm{O}(\mathrm{g}) \) ? \( \Delta \mathrm{H}^{\circ} \) (vapourisation) = \( 40.79 \mathrm{~kJ} / \mathrm{mol} \)
(a) \( 75.38 \)
(b) \( 80.98 \)
(c) \( 70.98 \)
(d) \( 45.89 \)
