Answer 1

The root-mean-square speed is the measure of the speed of particles in a gas, defined as the square root of the average velocity-squared of the molecules in a gas.

Answer 2

The root-mean-square speed is the measure of the speed of particles in a gas, defined as the square root of the average velocity-squared of of the molecules in a gas. ....The root-mean-square speed takes into account bothe molecular weight and temperature, two factors that directly affect the kinetic energy of a material.
