A glass contains a mixture of water and ice cubes, with a total mass of 0.2 kg and at a temperature of 0 C. The mass of ice cubes is 1/3 of the mass of the mixture in the glass. As a result of heat transfer from the surroundings at 20 Celsius degree to the mixture, the ice has molten and the temperature of the water increased to 20 Celsius degree. Assume the latent heat of melting ice equal to 333 kJ kg?

Question:

Calculate the entropy change of the substance in the glass and of the surroundings.
