One kg of air contained in a piston–cylinder assembly undergoes a process from an initial state where t1 5 300 k, 1 5 0.8 m3/kg to a final state where t2 5 420 k, 2 5 0.2 m3/kg. can this process occur adiabatically? if yes, determine the work, in kj, for an adiabatic process between these states. if no, determine the direction of the heat transfer. assume the ideal gas model for air.
