Question
Which among the following is an example of irreversible change?
Answer: Option C
:
C
Changes which can't be reversed or undone are called irreversible changes.
Structures made from sand can be broken down and we can obtain sand.
Paper planes can be unfolded and we can get back the paper in its initial state.
Ice can also change its form to water and can be converted back to ice on cooling. So they are reversible changes.
But after cutting a tree it can't be put back in its previous state. So it is an irreversible change.
