So we already spoke about the root mean square velocity of any set of points. Now, we're going to look specifically at the root mean square velocity for gases. Now, in gases, root mean square velocity is given by the following formula, which can be derived using calculus. 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.
