Calculate the amount of heat required to convert 1.00 kg of ice at -10°C at normal pressure to steam at 100°C. Specific heat capacity of ice = 2100 J kg−1 K−1 , latent heat of fusion of ice = 3.36 × 105 J kg−1 , specific heat capacity of water = 4200 J kg −1 K−1 and latent heat of vaporization of water = 2.25 × 106 J kg−1
