Because most of the volume occupied by a gas is empty space, a gas has a low density and can expand or contract under the appropriate influence. The fact that gas particles are in constant motion means that two or more gases will always mix as the particles from the individual gases move and collide with each other.

Density is the measure of how closely any given entity is packed, or it is the ratio of the mass of the entity to its volume. Change in pressure will be reflected in a change in density and vice-versa.
The pressure exerted by a static liquid depends only on the depth, density of the liquid, and the acceleration due to gravity. Gives the expression for pressure as a function of depth within an incompressible, static liquid as well as the derivation of this equation from the definition of pressure as a measure of energy per unit volume (ρ is the density of the gas, g is the acceleration due to gravity, and h is the depth within the liquid).
The density of a gold bar is the same at sea level, under the ocean, and at the top of mount everest. For a gas such as air, the density is impacted by changes in pressure, temperature, and humidity. Changes in air density can modify how easily an object moves and even can cause health problems.
