Question

The following figure shows a/an _____________________ change.

• A. Reversible
• B. Irreversible
• C. Both reversible and irreversible
• D. No change is happening.

Answer 1

The correct option is A

Reversible

A reversible change is a change which can be undone. So we always need to ask ourselves, "Is the reverse possible?"

The figure shows water cooled to get ice. So is the reverse possible? Clearly yes. The figure shows us that ice can be heated to get water. So this is a reversible change.
