4) Figure shows a gas contained in a vertical piston-cylinder assembly. The total mass of the piston (including shaft) is 100 kg. While the gas is slowly heated, the internal energy of the gas increases by 0.1 kJ, the potential energy of the piston-shaft combination increases by 0.2 kJ. The piston and cylinder are poor conductors, and friction between them is negligible. The local atmospheric pressure is 1 bar and approximate g as 10 m/s². The cross-sectional area of the piston is 0.01 m². Determine, (a) the work done by the gas, (b) the heat transfer to the gas, all in kJ. Patm= 1 bar Gas who 0.01 m²
