Air as an idea gas is compressed from a state where the pressure is 0.1 MPa and the temperature is 27oC to a state where the pressure is 0.5 MPa and the temperature is 207oC. Can this process occur adiabatically? If yes, determine the work per unit mass of air in kJ/kg, for an adiabatic process between these states. If no, determine the direction of heat transfer.
