An 8.5 gram ice cube at -10°C is put into a Thermos flask containing 200 cm3 of water at 30°C. Find by how much has the entropy of the cube-water system changed when equilibrium is reached? The specific heat of ice is 2220 J/kg•K. (The latent heat of fusion for ice is 333 kJ/kg and the specific heat of water is 4187 J/kg•K).
