1 g of water, of volume 1 cm3 at 100°C, is converted into steam at same temperature under normal atmospheric pressure (≃1 × 105 Pa). The volume of steam formed equals 1671 cm3. If the specific latent heat of vaporisation of water is 2256 J/g, the change in internal energy is,
1
167 J
2
2256 J
3
2423 J
