changes from one state to another without a change in chemical composition
What is the phase change in evaporation
Change of phase is caused 99% of the time by a change in temperature or pressure.
Phase change. Liquid phase to gaseous phase (evaporation) Liquid phase to solid phase (solidification, freezing) Solid phase to gaseous phase (sublimation9 Etc...
A phase change is an example of a physical change, not a chemical, nuclear, or covalent change. During a phase change, the substance undergoes a change in state (solid, liquid, gas) without any change in its chemical composition.
This phase change is called evaporation.
When ice melts and becomes water, that is a phase change. Same when water boils and becomes steam (a gas) that is also a phase change.
When a solid is heated, it will usually change to the liquid phase. This process is known as melting.

Changing the temperature or pressure of a material we can change the phase.
A change in phase is a physical process.
energy is either absorbed or released during a phase change
