5. Calculate the amount of heat needed to change the temperature of 2 kg of steam from 110 'C to -4 "C. Use the following in working this question: Specific heat of water = 1 kcal/kg."c Specific heat of ice = 0.5 kcal/kg."c Specific heat of steam = 0.5 kcal/kg."c Latent heat of fusion = 80 kcal/kg Latent heat of vaporization = 540 kcal/kg
