solid,liquid and gas
Changes in both temperature and pressure induce phase changes in water (and all other materials!).

When water changes from liquid to gas, this phase is known as vaporization.

Water changes phase.
explain why phase changes are reversible for solid to liquid and gas to liquid
Liquid to solid
For example after phase changes.
Physical, as it remains water.
No. Water freezing into ice is a good example of a "phase change". Ice can melt back into water, so we know that the phase change is not permanent!

These are phase changes - All the energy that is added at this time is used to change the phase of the substance.
