Question

Irreversible changes are temporary changes.

• A. True
• B. False

Answer 1

The correct option is B False

Irreversible changes are the changes in which the original substance cannot be obtained back from the newly formed substances. Hence, all irreversible changes are permanent changes. For example, paper when burnt changes into ash and hence, cannot be re-obtained from ash. Hence, burning of paper is a irreversible change.
