1. The problem statement, all variables and given/known data
Calculate Speed (v sub mp) and rotation speed ([tex]\omega[/tex] 2. Relevant equations (v sub mp) =Sq rt (2kT/m) <V>= 2/ (sqr rt pi )(V sub mp) Vrms = sq rt (3/2) X V sub mp How do I relatate these to rotational speed????? 3. The attempt at a solution Yo mamma The numbers came out correct where V sub mp < <V> <vrms But what about poor little omega... Thanks chaps

by the way make the question clear? is the gas mono or di or polyatomic? use the concept of rotational degrees of freedom of gas molecules.

Relationship between most probable speed & rotation speed (gas)
Monatomic :) I will look at degrees of freedom for monatomic gases.
