How much thermal energy is required to change a 40 g ice cube from solid at —10 °Cto steam at 110°C .
[Assume latent heat of fusion for water = 80 kcal / kg,
specific heat of water = 1 k cal / kg ° C ,
specific heat of Ice =0.5 kcal kg °C ,
specific heat of steam =0.48 kcal / kg° C ,
latent heat of vaporisation of water— 540 kcal / kg °C ]
