Mean square speed formula
WebThe vrms is the square root of the average of the squares of the speeds of the molecules: ( v2) 1/2. From equation (19) the vrms is (3 RT / M) 1/2. At 20° C the value for air ( M = 29) is 502 Read More velocity Table of Contents Home Science Physics Matter & Energy velocity mechanics External Websites Written and fact-checked by WebThe root-mean-square speed is the square root of the mean of the squares of the velocities. This quantity is defined so that addition of squares of velocities will not give zero unlike average. Since number of molecules is very high hence …
