Relationship between most probable speed & rotation speed (gas)

  1. Jan 27, 2011 #1
    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.

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