Pick the change that can be reversed from the following
A. Cutting of trees

B. Melting of ghee

C. burning of candle

D. Blooming of flower

Answer :

Melting of ghee is a physical change. In this, only the physical state of ghee changes from solid to liquid state and this change can be reversed, upon cooling.

All the other options include physical as well as chemical change, and hence cannot be reversed back.


● When we cut trees, they are physically separated into two parts, and also the chemical bonds are broken, changing their chemical properties.


● The burning of a candle decreases it’s length as a physical change and involves combustion as a chemical change.


● Blooming of a flower changes its physical state from bud to an open flower and has the role of some chemical substances, which can not be changed back to original form.
