Air with a temperature of 27 °C receives heat at constant

Air with a temperature of 27 °C receives heat at constant volume until the temperature reaches 927°C. The specific heat of air varies with temperature as Cp = 0.9167 + (2.577 x 10^-4) (3.974 x 10^-8) T² in kJ/kg-k a. Find the change of internal energy in kJ/kg. b. Find the change of enthalpy in kJ/kg.
