the water cycle-it changes forms for various reasons, when the sun heats water, it turns to water vapor which is a gas, and rises to the sky where it cools down into liquid particles, light enough to stay floated in the air, until its released as rain to the ground. with snow it can either be melted and then evaporated, or the sun can cause snow to evaporate snow without even turning to liquid. and transpiration is when the water on trees and other plants is evaporated. (but all of these start with the SUN. so you can say the cause of phase changes always starts with the sun)
Usually heat.
The phase change for liquid to gas is vaporization, which includes evaporation and boiling.Evaporation - The change of liquid molecules on the surface of a liquid to a gas.Boiling - The change of phase at or above the boiling point of the liquid, which takes place at nucleation sites within the liquid.
stays the same
Phase change is a physical change.
The opposite phase change is condensation. Evaporation is the change in phase from liquid to gas. Condensation is the change in phase from gas to liquid.
This phase change is called evaporation.

A phase change occurs when a material goes from a gaseous state to a liquid state, a liquid state to a solid state, or the above in reverse order.
The phase change is called deposition: water vapor changes directly to ice.
This is properly called "freezing". Occasionally, it can be called "solidifying", but that's not really correct.
Vaporization (evaporation) of water to a gas is caused by heating the water.
Evaporation is not a phase change form i is a process by which phase change.
By heating above 100 0C (at standard pressure) or by freezing below 0 0C.
