0.5 kg of a gas at temperature t1=20?C and pressurep1=0.1 MPa was contained in a cylinder with a piston.The gas was compressed (polytropic process) and a ratio of heatexchanged during the process to the work of compression was ¼. Findthe final temperature and pressure of the gas if 15 KJ of heat wastransferred to the surroundings. Specific heats at constant volumeand pressure were 654.67 J/Kg/K and 897.64 J/kg/K,respectively.
