A cylinder holds a fixed mass of gas. With the pressure kept constant at $1.3 \times 10^5\,\text{Pa}$, the gas increases in volume from $900\,\text{cm}^3$ to $1100\,\text{cm}^3$. How much work is done by the gas in this expansion?
- A$26\,\text{J}$
- B$130\,\text{J}$
- C$2600\,\text{J}$
- D$13\,000\,\text{J}$
