Question
Vrma′ Vav and Vmp are root mean squre, average and most probale speeds of molecules of a gas obeying Maxwellian velosity distribution. Which of the following statements is correct ?
Options
A.Vrma < Vav < Vmp
B.Vrma > Vav > Vmp
C.Vmp < Vrma < Vav
D.Vmp > Vrma > Vav
Solution
vrms = 
; vmp = 
vav =
So, vrms > vav > vmp
; vmp = vav =
So, vrms > vav > vmp
