A piston in a gas supply pump has an area of 400 cm^2. The pump moves the gas against a fixed pressure of 3000 Pa. During part of its stroke, the piston moves a distance of 25 cm in one direction. How much work is done by the piston during this movement?

1. A30 J
2. B3.0 \times 10^3 J
3. C3.0 \times 10^5 J
