Question

what is physical change​

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

Answer:

A physical change alters the form of a substance but does not change it to another substance.

1. It changes shapes and size
2. It dissolves
3. It changes phase (freezes, boils, evaporates)

Eg. Melting of wax is a physical change.

Physical changes could include change in: texture, shape, size, colour, odor, volume, mass, weight and density.
