Answer 2

Hola

Here is your answer

Physical changes are reversible.

Physical changes are temporary and can be reversed back.

Examples of reversible changes -

1. Ice changing to water.

When Ice is heated it comes to its original phase that is water while when water is freezed it changes to ice. The change is temporary and the matter can be changed.


2. Another example is evaporation. When water is evaporated, it changes to different matter that is gas. But it still remains water and the change is temporary.


Hope it helps!
