Question

Group of answer choices

Substance changes its form but not its molecular composition.

A substance reacts differently with a chemical before and after the change.

An irreversible process takes place.

New atoms are introduced in the molecules of the substance.

Answer 1

The correct answer is:

Substance changes its form but not its molecular composition.

During a physical change, the substance may undergo a change in state (such as melting or boiling) or a change in appearance (like breaking or dissolving), but its molecular composition remains the same. The other options describe chemical changes or processes that are not characteristic of physical changes.
