Homework Help: Charles' Law problem

  1. Sep 7, 2015 #1
    1. The problem statement, all variables and given/known data
    A gas is kept at constant pressure. If its temperature is changed from 38 to 132°C, by what factor does the volume change?

    2. Relevant equations
    V1T2=V2T1

    3. The attempt at a solution
    V1*132=V2*38
    V2/V1=132/38
    V2/V1=66/19

    Am I just reading something wrong or did just use the wrong law or something?

    solved my problem. I needed to first convert the temp to kelvin then invert that number to get my factor.
