A quantity of gas has an initial pressure, volume and temperature of 1.4 MN/m? 0.14 m and 300 "C, respectively. The gas is expanded adiabatically to a pressure of 280 kN/m². Determine the mass of gas (b) the temperature of the gas after the expansion (c) the work transfer (d) the change of internal energy of the gas For the gas, take < = 1.04 kJ/kg K. c = 0.74 kJ/kg K. [(a) 1.14 kg: (b) 87.4 °C: (c) 179.5 kJ; (d) - 179.5 kJ] 0.45 kg of gas is expanded adiabatically until the pressure is halved and the temperature of the gas falls from 220°C to 130 °C. During the expansion there is a work transfer from 27 kJ. Determine the adiabatic index of the gas (b) the characteristic gas constant [(a) 1.408: (b) 0.272 kJ/kg K)
