Answer 2

Tip- We should also remember that sublimation is the process of converting a solid to a gas without converting it to a liquid.

After heating, benzoic acid converts to a gas rather than a liquid, which is known as sublimation.

Explanation: It is not flammable. Benzoic acid, camphor, and naphthalene are purified using the sublimation technique. Sublimation, like melting, freezing, and evaporation is a form of phase transition or a change in the state of matter.
