Average square speed in Maxwell—Boltzmann statistics ==================================================== For an ideal gas, the average square of speed is directly proportional to its temperature and inversely proportional to the mass of the gas. **Notation:** #. :math:`k_\text{B}` (:code:`k_B`) is :attr:`~symplyphysics.quantities.boltzmann_constant`. **Conditions:** #. The gas is in thermal equilibrium with the environment. #. The gas particles are distributed according to Maxwell—Boltzmann statistics. **Links:** #. `Wikipedia <https://en.wikipedia.org/wiki/Maxwell%E2%80%93Boltzmann_distribution#Typical_speeds>`__. .. py:currentmodule:: symplyphysics.laws.thermodynamics.average_square_speed_in_maxwell_boltzmann_statistics .. py:data:: average_square_speed Average square of the :attr:`~symplyphysics.symbols.classical_mechanics.speed` of gas molecules.
