Four kilograms of a certain gas is contained within a piston-cylinder assembly. The gas undergoes a process for which the pressure-volume relationship is: pV1.5 = constant The initial pressure is 3 bar, the initial volume is 0.1m³, and the final volume is 0.2m³. The change in the specific internal energy of the gas in the process is u2-u₁ =-4.6kJ/kg. Determine the net heat transfer for the process. P PVIS =constant U₂-u₁ = -4.6 kJ/kg Gas 2 PV1.5= Area = work constant
