Answer 2

An irreversible transformation is one that cannot be reversed.

During an irreversible shift, new materials are always created. At times, these innovative materials can be beneficial.

Heating

• Heating might result in an irreversible change. Heat is used to cook a raw egg, for example.

• It's impossible to turn a fried egg into a raw one.

Mixing

• When chemicals are mixed, they may undergo an irreversible change. When vinegar and bicarbonate of soda, for example, the combination changes and a large number of carbon dioxide bubbles occur.

• These bubbles, as well as the remaining liquid mixture, can't be turned back into vinegar or bicarbonate of soda.

Burning

• The act of burning is an irreversible alteration. When wood is burnt, ash and smoke are produced.

• You won't be able to re-create wood from ash and smoke.
