In a system similar to that shown in this image, the gas in the cylinder is at a pressure equal to 101000 Pa and  and the piston has an area of 0.1 meter squared. As energy is slowly added to the gas by heat, the piston is pushed up a distance of 6 cm. Calculate the work done by the expanding gas on the surroundings, assuming the pressure remains constant.

Question

In a system similar to that shown in this image, the gas in the cylinder is at a pressure equal to 101000 Pa and  and the piston has an area of 0.1 meter squared. As energy is slowly added to the gas by heat, the piston is pushed up a distance of 6 cm. Calculate the work done by the expanding gas on the surroundings, assuming the pressure remains constant. 

The image consists of two diagrams labeled "a" and "b", illustrating the compression of a gas in a cylinder.

**Diagram a:**
- A cylindrical container with a movable piston inside.
- The piston encloses a volume of gas inside the cylinder.
- The parameters labeled inside the cylinder are:
  - \( P \): Pressure of the gas.
  - \( V \): Volume of the gas.
  - \( A \): Cross-sectional area of the piston.

**Diagram b:**
- The same cylindrical container with the piston pushed further down.
- The movement of the piston is indicated by a downward arrow and a displacement labeled \( \Delta y \).
- The volume of gas in the cylinder decreases as the piston moves down.

This illustration demonstrates how the volume of a gas decreases when compressed by a piston in a cylinder, adhering to the principles of thermodynamics.
