What is the rms speed?

It is defined as the square root of the average velocity-squared of the molecules in a gas. It is given by the formula. where vrms is the root mean square of the speed in meters per second, Mm is the molar mass of the gas in kilograms per mole, R is the molar gas constant, and T is the temperature in kelvins.

Accordingly, what is the rms velocity?

The root mean square velocity (RMS velocity) is a way to find a single velocity value for the particles. The average velocity of gas particles is found using the root mean square velocity formula. μrms = (3RT/M)½

What does the kinetic theory state about the kinetic energy of gas molecules?

Kinetic Molecular Theory states that gas particles are in constant motion and exhibit perfectly elastic collisions. Kinetic Molecular Theory can be used to explain both Charles' and Boyle's Laws. The average kinetic energy of a collection of gas particles is directly proportional to absolute temperature only.
