A chemical change results in a change in chemical composition, while a physical change does not.
physical: water, wind, and temperature chemical: acid rain and rust
physical change are reversable
Physical changes are melting and boiling in this case; fire is a combustion, a chemical change.
Differences exist in chemical and physical properties.
The physical change will keep the atoms the same not moving but the chemical change will make it move around with energy.
During a chemical change the molecule is transformed; during a physical change the molecule is not transformed.
physical weathering is weathering that you can reverse and chemical weathering is where you can' reverse it.
Neither. Body heat is a result of chemical changes, but it's not itself a chemical change.
Physical changes involve a change in appearance, shape, or state without altering the chemical composition of the substance. Chemical changes, on the other hand, result in the formation of new substances with different chemical properties. Physical changes are usually reversible, while chemical changes are usually irreversible.
Physical changes involve a change in appearance or state of matter without altering the chemical composition, while chemical changes result in the formation of new substances with different chemical properties.
Getting a tattoo is obviously a physical change because you are only changing the appearance of your body. A chemical change is something that is caused by a chemical reaction. Although, the ink being put into your body is a "chemical" it is not changing the structure or function of your body.
