Question

2. What are reversible and irreversible changes ?
Give one example for each.​

Answer 1

Answer:

Reversible changes:

A reversible change is a change that can be undone or reversed. If you can get back the substances you started the reaction with, that's a reversible reaction

Examples: dissolving, evaporation, melting and freezing

irreversible changes:

A change is called irreversible if it cannot be changed back again. In an irreversible change, new materials are always formed.

Examples: burning, cooking, rusting of iron
