Question: 4 20 points a gas contained within a pistoncylinder assembly...

Question details

4. (20 points) A gas contained within a piston-cylinder assembly, initially at a volume of 0.2 m, undergoes a constant-pressure expansion at 3 bar to a final volume of 0.28 m, while being slowly heated through the base. The change in internal energy of the gas is Δυ=U2-U, 0.4 kJ. The piston and cylinder walls are fabricated from heat-resistant material, and the piston moves smoothly in the cylinder The local atmospheric pressure is 1 bar. For the gas as the system, evaluate work and heat transfer, each in kJ.
