condensation
thats evaporation and heat causes it
A liquid is transformed in a gas.
evaporation
it changes when it gets cold
The process by which radiant energy from the sun causes a liquid to change into a gas is called evaporation. When sunlight shines on a liquid, it provides the energy needed to break the bonds holding the liquid molecules together, allowing them to escape into the air as gas.
To change a gas to a liquid, you need to lower the temperature of the gas below its boiling point while keeping the pressure constant. This process is known as condensation and it causes the gas particles to slow down and come together to form a liquid.
Boiling refers to the application of heat that causes a liquid to change into gas.
An increase in temperature typically causes matter to change from a solid to a liquid or from a liquid to a gas. A decrease in temperature often results in the opposite transition, causing matter to change from a gas to a liquid or from a liquid to a solid.
Gas turns to liquid when energy is lost. The density of a gas is much less that the density of a liquid. Thus, when energy is lost and the particles of the gas are able to condense, it becomes a liquid.
The addition of heat or reduction in pressure can cause a substance to change from either a solid (sublimation) or liquid (evaporation) into a gas.
When heat is added to a liquid, it causes the molecules in the liquid to gain energy and move faster. This increased movement causes the liquid to change into a gas through a process called evaporation or boiling.
heat..high temperature.. this is called EVAPORATION.
