Which property of gases allows them to be stored at high concentrations in a bottle of air freshener?

Answer;

Compressibility

Compressibility is the property of gases that allow them to be stored at high concentrations in a bottle of air freshener.

Explanation;Gases possess various characteristics which includes; they are easy to compress, occupy more space than liquids and solids, and also they expand to fill their containers.Gases are compressible because most of the volume of a gas is composed of the large amounts of empty space between the gas particles. This allows gas particles  to move freely to fit into the gaps of space between them.
