Camphor in nitrogen gas is a type of solution

Solid-Gas

The correct answer is option 2. Solid-Gas.

The interaction between camphor (\(C_{10}H_{16}O\)) and nitrogen gas (\(N_2\)) forms a type of solution, particularly a solid-gas solution.

A solid-gas solution, also known as a solid-vapor solution or sublimation solution, is formed when a solid solute (in this case, camphor) disperses and mixes with a gas solvent (in this case, nitrogen gas) to form a homogeneous mixture.

In the case of camphor and nitrogen gas, solid camphor is placed in a container containing nitrogen gas. At room temperature, camphor undergoes sublimation, a process where it transitions directly from the solid phase to the gas phase without passing through the liquid phase.

As camphor sublimes, its vapor molecules disperse and mix with the nitrogen gas molecules in the container. The resulting mixture consists of camphor vapor molecules uniformly distributed throughout the nitrogen gas. This homogeneous mixture constitutes a solid-gas solution.

The camphor molecules are not chemically bonded to the nitrogen gas molecules but are instead dispersed among them, similar to how solute molecules are dispersed in a liquid solvent in a liquid solution.

Solid-gas solutions exhibit properties of both the solid solute and the gas solvent. In the case of camphor and nitrogen gas:

The camphor molecules retain their molecular structure and characteristics in the vapor phase, contributing to the overall properties of the mixture.

The nitrogen gas molecules provide the medium in which the camphor vapor molecules are dispersed.

Solid-gas solutions are typically characterized by the concentration of the vapor phase, which depends on factors such as temperature, pressure, and the vapor pressure of the solute.

In summary, the interaction between camphor (solid) and nitrogen gas forms a solid-gas solution, where camphor vapor molecules are dispersed and mixed with nitrogen gas molecules to form a homogeneous mixture. This type of solution is essential in processes such as sublimation and gas-phase reactions involving solid substances.
