Calculate change in internal energy and enthalpy of air

Fifty grams of air (ideal gas, M = 29 kg/kmol, k = 1.4) is enclosed in a rigid vessel of 20 L. Air is heated from 20 to 150?C. (a) Find the initial and final pressures (kPa) of air, and (b) calculate the change in internal energy and enthalpy (kJ) of air (i) using values from Table A-22 and (ii) assuming constant specific heats.
