Compressibility is the measure of how much a given volume of matter decreases when placed under pressure. If we put pressure on a solid or a liquid, there is essentially no change in volume… The kinetic-molecular theory explains why gases are more compressible than either liquids or solids.

As the gas molecules move away from one another there exists a lot of space in between them. So they are said to be more compressible than solids and liquids. In gases that are less dense, the pressure of the gas is independent of the properties and nature of the gas. Compared to liquids and solids, gases have low densities.

Gas compressibility, or isothermal gas compressibility, is also called the coefficient of isothermal compressibility of gas. It is defined as the relative change in the volume of the gas with respect to the change in pressure at constant temperature. It is expressed in units of reciprocal pressure (usually psi−1 ).

All gases are compressible because they consist largely of empty space with a few particles scuttering around through it, therefore the gas can be compressed by pushing the particles closer together so the whole occupies less space.

The compressibility of fluid is basically a measure of the change in density that will be produced in the fluid by a specified change in pressure. Gases are, in general, highly compressible whereas most liquids have very low compressibility.

There are three regimes that affect the compressibility factor: the value of Z tends toward 1 as the gas pressure approaches 0, where all gases tend toward ideal behavior the value of Z is less than 1 at intermediate pressures because the intermolecular forces of attraction cause the actual... the ...

The compressibility factor (Z) is a useful thermodynamic property for modifying the ideal gas law to account for behavior of real gases. It is a measure of how much the thermodynamic properties of a real gas deviate from those expected of an ideal gas.

Gas is quite compressible, and when you stack it vertically you find that the pressure exerted by the gas stacked above it changes via both linear and nonlinear mechanisms. The primary nonliner mechanism is called “compressibility” (symbol “ Z ”) which is fundamentally a measure of the amount that a gas deviates from ideal gas behavior.
