11 kilogram of ice at -10 °C is heated and melted into water until water reaches a temperature of 50 °C. Determine how much heat is needed for this operation? The hot water is mixed with 1 kilogram of steam at 108 °C. Determine the resulting temperature of the mixture? The latent heat of vaporization of steam is 540 kcal/kg. The specific heat of water is 4186 J/Kg/C. The latent heat of fusion of ice is 80kcal/kg.
