At a normal temperature of about 25 o C it is liquid, but below 0 o C it will freeze and turn to ice. Water can be found in the gaseous state above 100 o C, this is called the boiling point of water, at which water starts to evaporate. The water turns to gas and is then odourless and colourless.
This is a lot of energy as it represents the same amount of energy needed to raise the temperature of 1 kg of liquid water from 0ÂºC to 79.8ÂºC. Even more energy is required to vaporize water; it would take 2256 kJ to change 1 kg of liquid water at the normal boiling point (100ÂºC at atmospheric pressure) to steam (water vapor). This example shows that the energy for a phase change is enormous compared to energy associated with temperature changes without a phase change.
