An insulated container contains a block of ice of mass 1 ton (US) (1 US ton is 907.2 kg) at -20oC. The insulation is removed, and the ice gradually melts to water and comes to thermal equilibrium with the surroundings at 20°C. Assuming the pressure to remain constant at 100 kPa, determine the heat transfer during.
(a) The sensible heating of ice.
(b) The melting of ice.
(c) The sensible heating of water.
