A boiler contains water at atmospheric pressure. Use the data below to calculate the work done by the system in producing 1\text{ kg} of steam (water vapour) at atmospheric pressure. Data: 1\text{ kg} of water at 100\ ^\circ\text{C} occupies 1.0 \times 10^{-3}\text{ m}^3 1\text{ kg} of steam at 100\ ^\circ\text{C} and at atmospheric pressure occupies 1.7\text{ m}^3

1. (A)0\text{ J}
2. (B)1600\text{ J}
3. (C)100 \times 10^3\text{ J}
4. (D)1.7 \times 10^5\text{ J}
