Water (0.12m) COPPER A 50-kg copper block initially at 80°C is dropped into an insulated tank that contains 0.120 m3 of water at 25°C. Determine the final equilibrium temperature and the total entropy change for this process. Properties: Take the density and specific heat of water as p-997 kg/m3 and cp-4.1SKJ/kgK, respectively, and the specific heat of copper as cp=0.386kJ/kgK (values at room temperature).
