Reversible change is a type of change that can be reversed back, which means, a substance can come back into its original state. Following are few examples of reversible changes:
Folding of paper.
Stretching of a rubber band.
Melting of Ice cubes.
Inflation of a balloon.
Melting of wax.
Physical changes are reversible and can be brought back to their original shape and size but chemical reactions are not reversible.
6. What is a change according to Chapter 6 of Class 6 Science?
A change is a minute modification that happens physically or chemically in a substance. The change can be either reversible or irreversible.
