There are three main states that a substance can exist as: solid, liquid and gas. The transition between these states occur when a substance is heated or cooled past their freezing/melting or boiling/condensing points.
Solid -> Liquid = Melting
Liquid -> Gas = Boiling
Gas -> Liquid = Condensing
Liquid -> Solid = Freezing

Matter changes state because of temperature and pressure. These quantities bring change.
Changes the temperature of the substance
These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.
In evaporation, a liquid such as water changes to a gaseous state. In sublimation, a solid such as ice changes driectly to a gas or vapor without going through a liquid state.
When any liquid changes to a solid it as too be frozen or cooled to such a state where the molecule join together to make one uniform state (aka soild)
A change of state: Solid <-> Liquid <-> Gas A change of state is a physical change.
through changes of energy
They aren't; a change of state is a physical change

Changes in the states of matter - or phase changes - do entail changes in volume.
Matter changes state because of pressure and temperature.
When water boils it changes from a liquid state to a gaseous state.
These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.
The density changes.
The only changes of state in pure boiling water is from liquid to gas.
