Question

what is a physical change??? please anyone answer​

Answer 1

Explanation:

Physical changes are changes affecting the form of a chemical substance, but not its chemical composition. Physical changes are used to separate mixtures into their component compounds, but can not usually be used to separate compounds into chemical elements or simpler compounds.

Answer 2

physical reaction occurs when molecules undergo a molecular rearrangement to produce a physical change. The molecules are not chemically altered. ... So, the difference is that with a physical reaction, a chemical change in the molecule is not observed, but a physical change is observed.
