A thermally insulated piece of metal is heated under atmosphere by an electric current so that it receives electric energy at a constant power P. This leads to an increase of the absoulute temperature T of the metal with time t as follows `T=a^(1/4)`. then the heat capacity `C_(p)` is

A thermally insulated piece of metal is heated under atmospheric pressure by an electric current so that it receives electric energy at a constant power P. This leads to an increase of absolute temperature T of the metal with time t as follows: T(t)=T_0[1+a(t-t_0)]^(1//4) . Here, a, t_0 and T_0 are constants. The heat capacity C_p(T) of the metal is
