Question

In any situation, a change can be

• A. Reversible
• B. Irreversible
• C. Both reversible and irreversible
• D. Where there is no alteration in state

Answer 1

Answer: (C)

Both reversible and irreversible

A paper boat can be made from a paper and then by unfolding it, it can be converted back to the same paper. Thus this is a reversible change. Whereas when a plane drawn on a paper is cut out, then it cannot be put back at the same position, this change is permanent. Hence this change is irreversible.
