State of matter is referring to a substances existence as a solid, liquid, or gas. So, a common example would be solid water (we call it ice) changing state to liquid water due to the addition of energy (possibly heat). If energy continues to enter the system the liquid water will change state again to become a gas (steam).
Four examples of changes in state are: solid to gas (sublimation), gas to solid (deposition), solid to liquid (fusion), and gas to liquid (condensation).
It means that although it changes, no new substances are formed. Examples of such changes are melting and other state changes, and dissolving.

Physical Changes
Change of the state of water from a solid (ice cubes) to liquid (water).
no
A change of state: Solid <-> Liquid <-> Gas A change of state is a physical change.
Changes in the states of matter - or phase changes - do entail changes in volume.
through changes of energy
They aren't; a change of state is a physical change
The density changes.
Matter changes state because of pressure and temperature.
When water boils it changes from a liquid state to a gaseous state.
