Calculate \(\Delta U, \Delta H, Q\) and \(W\) if \(1 \mathrm{~mol}\) of an organic liquid is converted reversibly into vapour at \(353 \mathrm{~K}\) by supplying heat from external source. The expansion of vapour takes place at the pressure of \(1 \mathrm{~atm}\). The heat of vaporization and the molecular weight of the liquid are \(380 \mathrm{~J} / \mathrm{g}\) and \(78 \mathrm{~g} / \mathrm{mol}\) respectively.
