Which one of the following statements is correct about camphor and ammonium chloride?

Question

Question

Answer 1

The correct answer is Both of them undergo sublimation.

Important Points

Both camphor and ammonium chloride are solid at room temperature.
But they are vaporised (gas phase) when heat is applied.
- This property is called Sublimation.

Key Points

Sublimation - Direct conversion of a solid into the vapour state is called sublimation.
The heat of sublimation - Heat required to change a unit mass of solid directly into vapour, at a given temperature, is called the heat of sublimation at that temperature.

Additional Information

Camphor:
- Colourless or white crystalline powder, flammable, waxy with a strong mothball-like odour.
- Molecular Formula: C₁₀H₁₆O.
- Organic compound.
Ammonium chloride:
- Molecular Formula: NH₄Cl
- Also, called sal ammoniac (White crystalline salt).
- Inorganic compounds and highly soluble in water, alcohol, methanol, glycerol, etc.
- Ammonium Chloride gives an acidic solution by dissolving in water.
- Inorganic compound.
