Question

A piece of paper is used to make a paper plane. Which type of change is this?

• A.
  
  Both reversible and irreversible change
• B.
  Permanent change
• C.
  Reversible change
• D.
  Irreversible change

Answer 1

The correct option is C

Reversible change
A reversible change is a change which can be undone.
When a paper is folded to make a paper plane, we have changed the shape of the paper. But, it is not permanent. We can unfold the paper and bring it back to its original shape. This makes it a reversible change.
