Reversible and non-reverible changes

Which changes are reversible and which are irreversible?

Matter changes states through energy (force or heat)

Solids can change to liquids through energy (heat or force).

For example: Ice changes to water when it gets warm

Liquids change to gas through energy (heat)

For example: When water gets boiling hot it evaporates and turns into water vapor (a gas) and rises up.

Can you turn ice into water?

Matter is made up of molecules.
