Question

using a suitable diagram explain the most probable speed ,the avg speed and the root mean square speed

Answer 1

Most Probable Speed :
                   The Speed possessed by the macimum number of molecules in a gien sample of gas is called most probalble. It is denoted by Ump

Ump =√(RT/M)

Avergare Speed :
       Average speed is the ration of sum of all speed of all gas molecueles to the total number of Moolecules

Uavg = U1 + U2 + U3 + ........................+Un / n =√(8RT/πM)

Root Mean Square Velocity (RMS):
          It is the root of mean of the sqaures of Speeds of all gas molecules is called RMS speed.

Urms = √(U₁² + U₂² + ................. Un²)/√n = √(3RT/M)
 * R= Universal Gas Constant
T = Absoulte Temperature
M = Molecular Weight
