Question

A 405-g sample of lead with specific heat cPb = 128 J/(kg · °C) at 87.0°C and a 220-g sample of silver with specific heat cAg = 230.0 J/(kg · °C) at 38.0°C are added to 0.500 kg of water at 22.0°C where specific heat of water cW = 4190 J/(kg · °C) in an insulated container. Assuming the system is thermally isolated, what is its final equilibrium temperature?
