0The kinetic theory describes a gas as a large number of submicroscopic particles (atoms or molecules), all of which are in constant rapid motion that has randomness arising from their many collisions with each other and with the walls of the container:
- Average Velocity, Straight Line. The average speed of an object is defined as the distance traveled divided by the time elapsed.
- Root-mean-square speed is the measure of the speed of particles in a gas which is most convenient for problem solving within the kinetic theory of gases. It is defined as the square root of the average velocity-squared of the molecules in a gas.
- The root mean square velocity (RMS velocity) is a way to find a single velocityvalue for the particles. The average velocity of gas particles is found using the root mean square velocity formula. μrms = (3RT/M)½
- m p - The most probable velocity at which the most molecules in a gas travel. The formula for most probable velocity is: v p = = Root mean square velocity - An equation to measure the typical velocity of molecules in a gas. v rms.
