One kg of nitrogen contained in a cylinder at a pressure of 7bar and temperature of 300K expands 4 times of its original volume. The process of expansion is assumed to take place at constant pressure. Calculate a) Initial volume b) Final temperature c) Work done d) Heat added. e) Change in internal energy. For nitrogen assume, Cp =1.045 kJ/kg K, R=0.296 kJ/kg K
