Now, I will spare you the calculus and simply give you the formula. But if you're curious about where this formula comes from, leave A comment and I'll Show you. So, VRMs is equal to the square root of three times R times T divided by M, where M is our molar mass of gas, t is our temperature in Kelvin, and R is the molar gas constant. Now, my goal is I want to use this VRMs to find the average kinetic energy. Because remember, kinetic energy of anything is given by one half times mass times V squared. Now, to find the kinetic average, I basically plug in my Dr meh into my D, and that will give me the average, because remember, this guy is the average or the quadratic average of my sets of points.
