Question

Which of the following is an example of reversible change?

• A. Molding clay to form a toy.
• B. Making a light mark on a paper with a pencil.
• C. Cutting a piece of paper.
• D. Ripening of fruits.

Answer 1

Answer: (A), (B)

The correct options are
A

Molding clay to form a toy.

B

Making a light mark on a paper with a pencil.

- Moulding clay to form a toy is a reversible change as the toy can be broken down, mixed with water to get clay again.

- Making a light mark on a piece of paper with a pencil is a reversible change as it can be erased.

- Cutting a piece of paper is an irreversible change because we cannot get the original paper after it is cut.

- Ripening of fruits is an irreversible change as once a fruit has ripened, it cannot go back to its unripe form.
