Homework Help: RMS and gas speed thing

  1. Nov 28, 2007 #1
    1. The problem statement, all variables and given/known data

    The rms speed of a sample of gas is increased by 8 percent.

    (a) By how much does the gas's temperature change? (given in %)
    (b) By how much does the gas's temperature change, assuming its volume is held constant? (%)

    2. Relevant equations

    rms = [tex]\sqrt{3KT/M}[/tex]

    3. The attempt at a solution

    I have no idea how to solve this. I set the left side of the equation equal to 0.08, and then I got lost from there. -__-
