Water at a temperature of 16°C enters an ice-making machine and emerges as ice cubes at a
temperature of -5°C. The melting point of ice is 0°C.
(a) Calculate the total energy removed from 1.0 kg of water as it cools from 16°C, changes into
ice, and then cools to -5°C.
specific heat capacity of liquid water = 4.2 x 103J/(kg°C)
specific latent heat of fusion of water = 3.4 x 105J/kg
specific heat capacity of ice = 2.1 x 103 J/(kg°C)
