  2. Gas laws - Wikipedia

    en.wikipedia.org/wiki/Gas_laws

    This law states that the rate at which gas molecules diffuse is inversely proportional to the square root of the gas density at a constant temperature. Combined with Avogadro's law (i.e. since equal volumes have an equal number of molecules) this is the same as being inversely proportional to the root of the molecular weight.

    Relationships between Boyle's, Charles's, Gay-Lussac's, Avogadro's, combined and ideal gas laws, with the Boltzmann constant k = ⁠ R / N A ⁠ = ⁠ n R / N ⁠ (in each law, properties circled are variable and properties not circled are held constant) The mathematical equation for Boyle's law is: =

  4. Avogadro's law - Wikipedia

    en.wikipedia.org/wiki/Avogadro's_Law

    The law is a specific case of the ideal gas law. A modern statement is: Avogadro's law states that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules." [1] For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are ...

  5. Charles's law - Wikipedia

    en.wikipedia.org/wiki/Charles's_law

    The law was named after scientist Jacques Charles, who formulated the original law in his unpublished work from the 1780s.. In two of a series of four essays presented between 2 and 30 October 1801, [2] John Dalton demonstrated by experiment that all the gases and vapours that he studied expanded by the same amount between two fixed points of temperature.

  6. Gay-Lussac's law - Wikipedia

    en.wikipedia.org/wiki/Gay-Lussac's_law

    These three gas laws in combination with Avogadro's law can be generalized by the ideal gas law. Gay-Lussac used the formula acquired from ΔV/V = αΔT to define the rate of expansion α for gases. For air, he found a relative expansion ΔV/V = 37.50% and obtained a value of α = 37.50%/100 °C = 1/266.66 °C which indicated that the value of ...

    Charles's law Charles's law (also known as the law of volumes) is an experimental gas law that describes how gases tend to expand when heated. A modern statement of Charles's law is: When the pressure on a sample of a dry gas is held constant, the Kelvin temperature and the volume will be in direct proportion. [103] Chemical bond

  8. List of eponymous laws - Wikipedia

    en.wikipedia.org/wiki/List_of_eponymous_laws

    Avogadro's law, one of the gas laws, states that: "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules." Babinet's principle, in physics, states that the diffraction pattern from an opaque body is identical to that from a hole of the same size and shape except for the overall forward beam intensity.
