The absolute pressure in the container when the monatomic ideal gas is placed under a piston is 1.17 × 10⁵ pa
The absolute pressure in the container will be:
= Po + mg/A
= 1.013 × 10⁵ + (50 × 9.8)/(π × 0.1²)
= 1.17 × 10⁵ pa
The volume of the gas will be:
= nRT/P
= 2 × 8 × 3.14 × (0 + 273)/(1.17 × 10⁵)
= 0.0388m³
The amount of work done by the gas during its expansion will be:
= 1.17 × 10⁵ × (0.053 - 0.0388)
= 1661J
