A closed vessel contains 2 kg of carbon-dioxide at temperature degree celsius and pressure 0.7 bar. Heat is supplied to the vessel till the gas occupies a pressure of 14 bar, Calculate (a) final temperature (h) work done on or by the gas, (e) heat added and (d) change in internal energy e) Change in entropy. Take specific heat of gas at constant volume as 0.657 kJ/kg K.
