The specification above is incomplete, because for any object or system the magnitude of the compressibility depends … See more

The isothermal compressibility is generally related to the isentropic (or adiabatic) compressibility by a few relations:
where γ is the heat capacity ratio, α is the volumetric coefficient of thermal expansion, ρ = N/V is t… See more

The Earth sciences use compressibility to quantify the ability of a soil or rock to reduce in volume under applied pressure. This concept is important for specific storage, when estimating groundwater reserves in … See more

The degree of compressibility of a fluid has strong implications for its dynamics. Most notably, the propagation of sound is dependent on the compressibility of the medium. See more

Compressibility is an important factor in aerodynamics. At low speeds, the compressibility of air is not significant in relation to aircraft design, but as the airflow nears and exceeds the speed of sound, a host of ne… See more

For ordinary materials, the bulk compressibility (sum of the linear compressibilities on the three axes) is positive, that is, an increase in pressure squeezes the material to a smaller volume. This conditi… See more
