Question

Naphthalene balls become smaller in size when kept exposed for a few days due to sublimation.

• A. True
• B. False

Answer 1

The correct option is A

Naphthalene balls become smaller in size when kept exposed for a few days due to sublimation i.e. they change their state from solid to gas, thereby getting smaller in size.

Sublimation is the transition from the solid phase to the gas phase without passing through an intermediate liquid phase.
