A gas contained within a simple piston-cylinder assembly with a fixed piston mass, initially at a volume of 0.3 m³, undergoes a quasi-equilibrium expansion at 1 bar to a final volume of 1 m³, while being slowly heated through the base. The change in internal energy of the gas is 0.85 kJ. The piston and cylinder walls are fabricated from heat-resistant materials for thermal insulation, and the piston moves smoothly in the cylinder without friction. By taking the gas as the system, (a) find the moving boundary work (W₁ = ₁² PdV) done by the gas, in kJ, and (b) the heat transfer between the system and its surroundings, in kJ.
