WebRoot mean square speed (v rms) is defined as the square root of the mean of the square of speeds of all molecules. It is denoted by v rms = √v 2. Equation (9.8) can be re-written as, From the equation (9.18) we infer the following (i) rms speed is directly proportional to square root of the temperature and inversely proportional to square ... Web22 Feb 2024 · The root-mean-square speed is the speed that corresponds to the average kinetic energy of the molecules.
