Question

Name the phenomenon which causes the following change:

The disappearance of camphor when exposed to air.

Answer 1

The disappearance of camphor, when exposed to air, is known as Sublimation.

• Sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
• For example - Camphor has a tendency to sublimate, so when it is heated it directly gets converted into gas.
