Soda is an example of a liquid-gas solution, as it contains carbon dioxide (a gas) dissolved in water (a liquid).
Air is an example of a gas-gas solution.
An example of a liquid-gas solution is carbonated water, where carbon dioxide gas dissolves in water. An example of a gas-gas solution is air, which is a mixture of various gases like nitrogen, oxygen, carbon dioxide, and others in the atmosphere.
There are a number of examples of solid in gas solutions, such as smoke, in which carbon and air are in the form of a solution. Automobile exhaust is another example of solid in gas solution. An example of such solution is Iodine vapors in the air.

An example of a solid and gas solution: hydrogen dissolved in palladium.
Gas in gas
gas-gas
A common example of a solid solution would be salt water. The salt (usually sodium chloride) is the solute and the water is the solvent. A common example of gas solution would be soda water (Seltzer or club soda). Soda water is a solution in which the gas, carbon dioxide, is the solute and water is the solvent.
Air. (Oxygen, Carbon Dioxide)
When a liquid is dissolved in a gas, it results in a solution known as a liquid-gas solution or mist. The liquid particles become dispersed throughout the gas, creating a homogeneous mixture. An example of this is water vapor in air.
An example of a solid and gas solution: hydrogen dissolved in palladium.
A solution that is composed completely of gas is carbon dioxide. Hydrogen dioxide is also a solution composed completely of gas.
