A thermally insulated piece of metal is heated under atmospheric pressure by an electric current so that it receives electric energy at constant power P This leads to an increase in the absolute temperature T of the metal with time t as T t T 1 a t to where a to and To are constants The heat capacity Cp T of the metal is A 4P aTo
