Evaporation

From the Simple English Wikipedia, the free encyclopedia that anyone can change

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 will just "kill" each and eventually they become so far apart that they become a gas. The more heat there is the faster evaporating is. Water boils at around 100 degrees Celsius. There are many factors that affect the evaporation rate. Some liquids evaporate at different temperatures, such as alcohol, which evaporates at 87 degrees celsius. Basically, water dries up and disapears in the air.
