What are reversible changes? Give two examples of changes, which can be reversed.

Reversible Changes

Reversible changes are those changes that can be undone or reversed to get back the original substance.

In such changes, the substance can return to its previous state by changing the conditions.

Examples
Ice changing into water and water freezing into ice
When ice is heated, it melts into water. When the water is cooled, it turns back into ice.
Stretching a rubber band
When we stretch a rubber band and release it, it returns to its original shape.

These changes are temporary and reversible.
