16 \times 10^{-3}\text{ m}^3 of a gas at a pressure of 1750\text{ kPa} is contained in a cylinder. The gas is expanded at constant pressure until the volume becomes 140 \times 10^{-3}\text{ m}^3. How much work is done by the gas?

1. (A)217\text{ kJ}
2. (B)245\text{ kJ}
3. (C)273\text{ kJ}
4. (D)347\text{ kJ}
