  2. Gassmann's equation - Wikipedia

    en.wikipedia.org/wiki/Gassmann's_equation

    Gassmann's equations are a set of two equations describing the isotropic elastic constants of an ensemble consisting ... Correct the bulk density for the change in ...

  3. Bulk modulus - Wikipedia

    en.wikipedia.org/wiki/Bulk_modulus

    When the gas is not ideal, these equations give only an approximation of the bulk modulus. In a fluid, the bulk modulus K {\displaystyle K} and the density ρ {\displaystyle \rho } determine the speed of sound c {\displaystyle c} ( pressure waves ), according to the Newton-Laplace formula

  4. Bulk density - Wikipedia

    en.wikipedia.org/wiki/Bulk_density

    The density of quartz is around 2.65 g/cm 3 but the (dry) bulk density of a mineral soil is normally about half that density, between 1.0 and 1.6 g/cm 3. In contrast, soils rich in soil organic carbon and some friable clays tend to have lower bulk densities ( <1.0 g/cm 3 ) due to a combination of the low-density of the organic materials ...

    en.wikipedia.org/wiki/Density

    From the equation for density ... solid, or a different gas or gaseous mixture. The bulk volume of a material —inclusive of the void space fraction— is often ...

  6. Specific volume - Wikipedia

    en.wikipedia.org/wiki/Specific_volume

    For a substance X with a specific volume of 0.657 cm 3 /g and a substance Y with a specific volume 0.374 cm 3 /g, the density of each substance can be found by taking the inverse of the specific volume; therefore, substance X has a density of 1.522 g/cm 3 and substance Y has a density of 2.673 g/cm 3. With this information, the specific ...

  7. Compressibility - Wikipedia

    en.wikipedia.org/wiki/Compressibility

    The particles in real materials interact with each other. Then, the relation between the pressure, density and temperature is known as the equation of state denoted by some function . The Van der Waals equation is an example of an equation of state for a realistic gas. = (,).

  8. Ideal gas law - Wikipedia

    en.wikipedia.org/wiki/Ideal_gas_law

    Isotherms of an ideal gas for different temperatures. The curved lines are rectangular hyperbolae of the form y = a/x. They represent the relationship between pressure (on the vertical axis) and volume (on the horizontal axis) for an ideal gas at different temperatures: lines that are farther away from the origin (that is, lines that are nearer to the top right-hand corner of the diagram ...

  9. Number density - Wikipedia

    en.wikipedia.org/wiki/Number_density

    Using the number density of an ideal gas at 0 °C and 1 atm as a yardstick: n 0 = 1 amg = 2.686 7774 × 10 25 m −3 is often introduced as a unit of number density, for any substances at any conditions (not necessarily limited to an ideal gas at 0 °C and 1 atm).
