Question

Which among the following is a reversible change?

• A. Formation of curd
• B. Baking bread.
• C. Orange juice is frozen to make ice lollies.
• D. Chopping off a mango into pieces

Answer 1

The correct option is C Orange juice is frozen to make ice lollies.

Changes that can be undone are called reversible changes. In the above-given options, only orange juice, which is frozen into ice-lollies, can be melted to give back the orange juice. So, it is a reversible change.
All of the other changes are irreversible.
