A sample of 0.6 kg of water at 90°C is placed in a container with 0.6 kg of water at 5 °C. After the water comes to thermal equilibrium. A 0.2 kg sample of tin at 20°C is then placed in the container. What will be the new temperature of the mixture? Use C = 4182 J/kgK for the specific heat of water and use C = 210 J/kgK for the specific heat of tin.
