Agas contained within a piston-cylinder assembly, initially at a volume of 0.1 m3 , undergoes a constant-pressure expansion at 2 bars to a final volume of 0.12 m3 , while being slowly heated through the base. the change in internal change of the gas 0.25 kj. the piston and cylinder walls are fabricated from heat-resistant material and the piston moves smoothly in the cylinder. for the gas as the system, evaluate work and heat transfer each in kj (neglect the potential energy change and kinetic energy change).
