Evaporation
Particles of liquids gain more energy and move around faster when heated. This movement causes them to expand. The particles eventually break away from one another. The liquid reaches this state at its boiling point, or the temperature at which the liquids turn into gas. Different liquids have different boiling points.
If you have heated water in an uncovered pan, you may have noticed that the water spills out of the pan when it reaches its boiling point at the temperature of 100 degrees Celsius ( ºC ). If you do not turn off the heat, the water will start to evaporate and turn into gas.
Evaporation is the process by which a phase of matter changes from liquid to gas or vapor. This takes place at temperatures below the boiling point. The rise in temperature causes the rate of evaporation to increase. Water evaporates when you boil it. Evaporation is also observed when wet clothes are dried under the sun.
