A cylinder is heated, causing the air inside to expand at a constant pressure of 2.2 × 10^5 Pa. The expansion of the air causes the piston to rise through a vertical distance of 0.50 m, doing 11 kJ of work. Frictional forces are negligible. What is the cross-sectional area of the piston?

1. A1.0 × 10^–4 m^2
2. B2.5 × 10^–2 m^2
3. C5.0 × 10^–2 m^2
4. D1.0 × 10^–1 m^2
