Physical Changes
A change of state: Solid <-> Liquid <-> Gas A change of state is a physical change.
changes in states of matter are physical changes, as they do not affect the chemical properties of the substance
They aren't; a change of state is a physical change
Yes. Chemical changes are changes in what things are made of, physical changes are changes of physical localization or state of matter ( liquid, solid, or gas)
Physical changes are reversible changes, such as change of state (boiling, melting etc), chemical changes are when something undergoes a reaction changing it's chemical makeup.
both, but more physical than chemical
No, changes of state such as this are physical changes.
Physical. changes of state (solid, liquid, gas) are physical changes.
Better to state it a biochemical change if required can state it chemical change
There are no physical changes. there are only chemical changes.
The identity of the property does not change so the physical properties change but not the chemical
Evaporation, Condensation, Melting and Freezing are all physical changes as only the state of matter is changing, rather than the chemical properties.
