Answer:

Irreversible changes are called permanent changes.

Explanation:

Changes occur in a matter due to certain physical and chemical reasons. Changes are said to be permanent if the original substance cannot be obtained. Permanent changes are mostly chemical changes. There is a change in the morphology of the constituting substances.

As a result, a new substance is formed which may or may not be in the same state of matter as the previous change. E.g. Reaction between sodium hydroxide and hydrogen chloride to form common salt and water.
