  2. Kinetic theory of gases - Wikipedia

    en.wikipedia.org/wiki/Kinetic_theory_of_gases

    Thus, the ratio of the kinetic energy to the absolute temperature of an ideal monatomic gas can be calculated easily: per mole: 12.47 J/K; per molecule: 20.7 yJ/K = 129 μeV/K; At standard temperature (273.15 K), the kinetic energy can also be obtained: per mole: 3406 J; per molecule: 5.65 zJ = 35.2 meV.

  3. Ideal gas law - Wikipedia

    en.wikipedia.org/wiki/Ideal_gas_law

    Hence, all the energy possessed by the gas is the kinetic energy of the molecules, or atoms, of the gas. = This corresponds to the kinetic energy of n moles of a monoatomic gas having 3 degrees of freedom; x, y, z. The table here below gives this relationship for different amounts of a monoatomic gas.

  4. Maxwell–Boltzmann distribution - Wikipedia

    en.wikipedia.org/wiki/Maxwell–Boltzmann...

    The kinetic theory of gases applies to the classical ideal gas, which is an idealization of real gases. In real gases, there are various effects (e.g., van der Waals interactions , vortical flow, relativistic speed limits, and quantum exchange interactions ) that can make their speed distribution different from the Maxwell–Boltzmann form.

  5. Maxwell–Boltzmann statistics - Wikipedia

    en.wikipedia.org/wiki/Maxwell–Boltzmann_statistics

    Maxwell–Boltzmann distribution is a specific application of Maxwell–Boltzmann statistics to the kinetic energies of gas particles. The distribution of velocities (or speeds) of particles in an ideal gas follows from the statistical assumption that the energy levels of a gas molecule are given by its kinetic energy:

  6. Temperature dependence of viscosity - Wikipedia

    en.wikipedia.org/wiki/Temperature_dependence_of...

    This transfer of momentum can be thought of as a frictional force between layers of flow. Since the momentum transfer is caused by free motion of gas molecules between collisions, increasing thermal agitation of the molecules results in a larger viscosity. Hence, gaseous viscosity increases with temperature.

  7. Kinetic energy - Wikipedia

    en.wikipedia.org/wiki/Kinetic_energy

    Kinetic energy is the movement energy of an object. Kinetic energy can be transferred between objects and transformed into other kinds of energy. [10] Kinetic energy may be best understood by examples that demonstrate how it is transformed to and from other forms of energy.

  8. Boltzmann constant - Wikipedia

    en.wikipedia.org/wiki/Boltzmann_constant

    The Boltzmann constant (k B or k) is the proportionality factor that relates the average relative thermal energy of particles in a gas with the thermodynamic temperature of the gas. [2] It occurs in the definitions of the kelvin (K) and the gas constant , in Planck's law of black-body radiation and Boltzmann's entropy formula , and is used in ...

  9. Joule–Thomson effect - Wikipedia

    en.wikipedia.org/wiki/Joule–Thomson_effect

    The internal energy is the sum of thermal kinetic energy and thermal potential energy. [12] Thus, even if the internal energy does not change, the temperature can change due to conversion between kinetic and potential energy; this is what happens in a free expansion and typically produces a decrease in temperature as the fluid expands.
