A sample of 10 g of liquid benzene at its boiling point is vaporised using a 12 V,
0.5 A electric supply. The normal boiling point and latent heat of vaporisation of benzene are
353.2 K and 30.8 * 10
3 kJ/kmol respectively. Determine: (a) the change in internal energy, (b)
the time required for complete vaporisation.
