Evaporation

From Wikipedia, the free encyclopedia

Evaporation is when a liquid becomes a gas. When the molecules in a liquid are heated, they move faster. This makes them full of energy and so the particles collide with each other, and eventually they become so far apart that they become a gas. The more heat there is the faster evaporation happens. Water boils at around 100 degrees Celsius. There are many factors that affect the evaporation rate. Different liquids evaporate at different temperatures. For example, al evaporates at 87 degrees Celsius. When water is evaporating, it transforms into a gas called water vapor. The reverse of evaporation is condensation. Evaporation is a very essential part of the water cycle. When water is boiling in a closed container, sometimes evaporation happens at the same time as condensation.
