A physical change is a change in chemical composition. A physical change is a change where chemical composition is not altered. Not all chemical changes are accompanied by a physical change, but some are. The same is true for the reverse.

Are phase changes physical or chemical in nature?
A phase change is a physical change. It is not a chemical change.
Are tarnishing and rusting physical or chemical changes?
Something that tarnishes goes through a chemical change versus a physical change.
What is one major difference in a physical change and a chemical change is?
Physical change, changes the appearance or the surface. Chemical change, changes the minerals inside the object. Physical deals with the appearance and the surface. Chemical changes the structure of the minerals inside the object.
Chemical changes can be reserved by physical change?
No, chemical changes can only be reversed by chemical means, not by physical means.
Are state changes physical or chemical changes?
A change of state: Solid <-> Liquid <-> Gas A change of state is a physical change.
Are all physical changes accompanied by chemical changes?
Not all chemical changes are accompanied by a visible physical change. Most chemical changes however will be accompanied by a physical change.
Is it true that Physical changes are often accompanied by changes in color or odor?
No, a chemical change is usually accompanied by a change in color or odor. A physical change is a change that is the same substance before and after and usually accompanied by a change in state of matter (evaporation, condensation, melting, freezing, sublimating, etc).
Are physical change accompanied by chemical change?
No
Is a burning wood into ashes and smoke a physical or chemical change?
Burning wood is a chemical change - although, like most chemical changes it is accompanied by a physical change. Usually we reserve the term physical changes for things like erosion, melting, or evaporation where no change in composition occurs.
Are phase changes physical or chemical in nature?
A phase change is a physical change. It is not a chemical change.
What are the changes that matter undergoes?
the changes that matter undergoes are the physical and chemical change by:R.yu
Is etching glass with acid a chemical or physical change?

What are two kind of changes in matter?
The two types are chemical and physical changes.
Are tarnishing and rusting physical or chemical changes?
Something that tarnishes goes through a chemical change versus a physical change.
If water is boiling is it a chemical change or a physical change?
It is a physical change. All phase changes are physical, not chemical. The chemical composition of water does not change when it changes from a liquid to a gas, or for that matter, to a solid.
Are phrase changes a chemical or physical change?
Physical change
