Question

Sodium chloride undergoes sublimation.

• A. True
• B. False

Answer 1

The correct option is B False

1. Sublimation: The process of conversion of a solid substance directly into its vapours on heating and vapour into solid on cooling is called sublimation.
2. Sodium chloride$\left(\mathrm{NaCl}\right)$ doesn’t form any fumes rather gets converted into the liquid form when heated gently
3. Since Sodium chloride$\left(\mathrm{NaCl}\right)$ does not show a direct transition from solid to gas, it does not undergo sublimation.

Therefore Sodium chloride undergoes sublimation is false.
