Question

Identify the reversible changes among the following:
Change 1 - Children inflating balloons
Change 2 - Farmers harvesting crops

• A. Only 1 is a reversible change.
• B. Only 2 is a reversible change.
• C. Both 1 and 2 are reversible changes.
• D. Neither 1 nor 2 are reversible changes.

Answer 1

The correct option is A Only 1 is a reversible change.

Reversible changes are changes that can be undone. Inflating balloons is a reversible change as the balloon comes back to its original shape and size once the air inside the balloon escapes out.

However, harvesting the crops in a field is not a reversible change. This is because once the crops are harvested, they cannot be joined to get the crop back.
