Question

Which of the following is NOT a feature of a physical change?

• A. It can be reversible.
• B. It can be temporary.
• C. No new substance is formed.
• D. The composition of the substance changes.

Answer 1

The correct option is D

The composition of the substance changes.

A physical change involves only changes in the physical properties of the substance which may be temporary or permanent. There is no new substance created in the process.

In a chemical change, the substances get converted to entirely new and different substances. So this means that the composition of the substances changes after a chemical change. This is not a feature of a physical change.
