When 3.00g of water at 100°c changes from the liquid to the gas phase at standard atmospheric pressure, it's change in volume is 2.45×10*-3 m³. The latent heat of vaporisation of water is 2260 Km/kg. i. How much heat must be added to vaporise the water? ii. How much work is done by the water against the atmosphere in it's expansion? iii. What is the change in the internal energy of the water?
