# Relationship between most probable speed & rotation speed (gas)

## Homework Statement

Calculate Speed (v sub mp) and rotation speed ($$\omega$$

## Homework 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?????

## 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.

Monatomic :-) I will look at degrees of freedom for monatomic gases.
