(a) An 88-litre gas cylinder is filled with propane gas at a pressure of 1.15 MPa and 18°C. The propane is used to fuel a gas burner. After some time, the pressure and temperature are 210 kPa and 23°C respectively. Determine the mass of propane used. The molar mass of propane is 44 g/mole. (b) A piston-cylinder device filled with air at 365 kPa and 12°C, has an initial volume of 1.3 litres. The air is expanded at constant pressure to a volume of 3.6 litres and 516"C. Determine the amount of heat and work involved in this process and state whether the heat and work are into, or out of the gas.
