Question

Define physical change…​

Answer 1

Answer:

Change in which only physical properties of a substance change and no new substance is formed is called Physical Change. Most of the physical changes are reversible, this means we can get the substance back even after the change.

Answer 2

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.
