Q:

# How do you calculate root mean square velocity?

A:

Root mean square velocity is calculated using the Maxwell-Boltzmann velocity distribution equation, which describes the speed distribution of particles that behave like an ideal gas. It assists with solving mathematical problems related to the kinetic theory of gases.

To solve for the root mean square velocity requires knowing the molar mass of the gas in kilograms per mole, the temperature of the gas in Kelvin, and either the molar gas constant or the Boltzmann constant. A higher gas temperature results in a higher mean velocity. The root mean square velocity is useful in calculating the speed of both ideal and molecular gases.
