How much energy is required to heat 8.6kg of ice from -20c to steam at 120c The specific heat capacity of ice is 2.097j/kgc The latent heat of fusion of ice is Lt=3.33 x10j/kg The specific heat capacity of water is 4186j/kgc The latent heat of vapourization of water is Lv= 22.6 x 10j/kg Specific heat capacity of steam is 1996j/kgc 1. The heat energy need to raise the temperature of ice to 0c in joules= 2. The heat energy needed to convert ice to water at 0c in joules= 3. The heat energy needed to raise the temperature of water from 0c to 100c in joules= 4. The heat energy needed to convert water to steam at 100c in joules= 5. The heat energy needed to raise the temperature of steam from 100 to 120c in joules = 6. Using the answers above, the total energy to convert ice at -20c to steam at 120c in mega joules=
