Question

Which among the following is an example of reversible change?

• A. Making a sand castle
• B. Making an omelette
• C. Burning gasoline
• D. Cutting a tree

Answer 1

The correct option is A

Making a sand castle

Structures made from sand can be broken back to sand, so it is a reversible change. Conversion of an egg to omlette, burning of gasoline, and cutting a tree are irreversible changes as we cannot get the egg, gasoline, and tree back in their original state.
