A hot copper block (50 kg) initially at 80 C is dropped into 0.12 m3 water (25 C) in an insulated tank. The density and specific heat of water at 25 C are = 997 kg/m3 and cp = 4.18 kJ/kg. C. The specific heat of copper at 27 C is cp = 0.386 kJ/kg. C. The tank is insulated and there is no heat transfer. a) Determine the final equilibrium temperature of the tank, i.e. final temperatures for
