Question

In a physical change :

• A. new substances are not formed
• B. reaction is reversible
• C. change is temporary
• D. All of the above

Answer 1

The correct option is D All of the above

Physical changes in a substance do not form new substances, these reactions are reversible and the change is temporary.

Physical changes are the changes affecting the form of a chemical substance, but not its chemical composition. They are used to separate mixtures into their component compounds, but cannot usually be used to separate compounds into chemical elements or simpler compounds.
