An insulated Thermos contains 170 cm3 of hot coffee at 82.0°C. You put in a 13.0 g ice cube at its melting point to cool the coffee. By how many degrees has your coffee cooled once the ice has melted and equilibrium is reached? Treat the coffee as though it were pure water and neglect energy exchanges with the environment. The specific heat of water is 4186 J/kg·K. The latent heat of fusion is 333 kJ/kg. The density of water is 1.00 g/cm3.

An insulated Thermos contains 135 g of water at 86.5 ˚C. You put in a 7.06 g ice cube at 0.00 ˚C to form a system of ice + original water. The specific heat of liquid water is 4190 J/kg•K; and the heat of fusion of water is 333 kJ/kg. What is the net entropy change of the system from then until the system reaches the final (equilibrium) temperature?

An 12 g ice cube at -19?C is put into a
Thermos flask containing 100 cm3 of water at 20?C. By how much has
the entropy of the cube-water system changed when a final
equilibrium state is reached? The specific heat of ice is 2200 J/kg
K and that of liquid water is 4187 J/kg K. The heat of fusion of
water is 333 × 103 J/kg.
