Physical changes
Why we call reversible changes, physical changes?
Reversible changes usually change the physical appearance of a substance. Therefore, reversible changes are also called physical changes.
Characteristics of a reversible change
A reversible change changes how a substance looks or feels (changing the physical appearance), and it is easy to turn it back again. A reversible change may change the state of a substance such as, solid, liquid and gas. However, a reversible change does not change the amount of matter in a substance. Also, a reversible change doesn’t produce new substances.
E.g. – Water can change into ice. Ice can change into water. Here, only the state of the substance liquid water changes, but not the substance water.
