You put 50 kg of aluminimum at 180°C into 300 kg of water at 20°C. The alu- minium and water come to the same equilibrium temperature. Calculate the equilibrium temperature, if no energy is lost. Calculate the entropy change of the aluminium and of the water, and the total entropy change. Cwater = 4186 J kg-¹ K-¹, Calum = 900 J kg-¹ K-¹, You put 50 kg of aluminimum at 180°C into 300 kg of water at 20°C. The alu- minium and water come to the same equilibrium temperature.
