Question

Camphor in nitrogen gas is a type of solution:

• A. Gas – Gas
• B. Solid – Gas
• C. Liquid – Gas
• D. Solid – Liquid

Answer 1

The Correct Option is B

Camphor in nitrogen gas is a type of solution where camphor is the solute and nitrogen gas is the solvent. In this scenario, camphor is in solid form, and nitrogen is in gaseous form. Therefore, this type of solution is classified as Solid – Gas.

Components	State
Solute (Camphor)	Solid
Solvent (Nitrogen)	Gas

The correct answer is: Solid – Gas.

Answer 2

The solution of camphor in nitrogen gas is classified as a Solid – Gas solution. Here's a detailed explanation:

Components:

• Solute: Camphor (solid)
• Solvent: Nitrogen gas (gas)

Process:

Camphor, in its solid state, undergoes sublimation. Sublimation is the process where a solid transitions directly into a gas phase without passing through the liquid phase. This occurs because camphor has a relatively high vapor pressure, allowing it to readily vaporize. The camphor vapor then mixes uniformly with the nitrogen gas, creating a homogeneous mixture.

Why it's a Solid – Gas Solution:

The key factor is the initial state of the solute and the final state of the mixture. Camphor starts as a solid, and the resulting mixture is a gas. Therefore, it's a solid dissolving into a gas. This distinguishes it from other types of solutions, such as:

• Gas – Gas: Both solute and solvent are gases (e.g., air).
• Liquid – Gas: A liquid dissolves in a gas (e.g., water vapor in air).
• Solid – Liquid: A solid dissolves in a liquid (e.g., salt in water).

In this case, the solid camphor is dispersed as a gas throughout the nitrogen gas, making it a solid-gas solution.
