A 50 g ice cube initially at - 30 0C is heated until it has completely been changed to steam at 120 0C, how much heat energy in calories has been added? ( Specific heat of ice is 0.5 ca/g 0C and that of steam is 0.48 cal/ g 0C , that of water is 1 cal/g 0C ; Latent heat of fusion of ice is 80 cal/g, Latent haet of vaporization is 540 cal/g ).
