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.
As Chemistry is a part of Physics, the answer is: Yes.
Not all chemical changes are accompanied by a visible physical change. Most chemical changes however will be accompanied by a physical change.
Not all physical changes accompanied by a chemical change. Melting and freezing are two physical changes that are not accompanied by a chemical change.
no that's what my science teacher said
A phase change is a physical change. It is not a chemical change.
Something that tarnishes goes through a chemical change versus a physical change.
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.
No, chemical changes can only be reversed by chemical means, not by physical means.
A change of state: Solid <-> Liquid <-> Gas A change of state is a physical change.
Not all chemical changes are accompanied by a visible physical change. Most chemical changes however will be accompanied by a physical change.
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).
No
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.
A phase change is a physical change. It is not a chemical change.
the changes that matter undergoes are the physical and chemical change by:R.yu
It is a physical change caused by chemicals. Chemical changes are phyiscal changes.
The two types are chemical and physical changes.
Something that tarnishes goes through a chemical change versus 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.
Physical change
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.
