They aren't; a change of state is a physical change
Physical Changes
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.
how temperature can bring about changes in the state of matter
The only changes of state in pure boiling water is from liquid to gas.
1) melting-solid state changes into liquid state and 2)freezing-liquid state changes into solid state
No, changes in state of matter (such as melting, freezing, boiling) are physical changes, not chemical changes. Chemical changes involve the formation of new substances with different chemical properties.
The density changes.
State changes are physical changes because they involve a change in the physical properties of a substance, such as its form or state of matter (solid, liquid, gas). No new substances are formed during a state change, making it a physical change rather than a chemical change.
