Answer :
the square root of the mean of the squares of speeds of gas molecules is called as rms velocity
the square root taken over the average of squares of velocities of individual particles is the rms (root mean square velocity) of the body or medium.
Its units are same as that of velocity. It is an aggregate average. It is a measure of energy in the medium.
