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 poly-atomic? 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.
