Chemistry Gas Laws

  1. Oct 16, 2011 #1
    1. The problem statement, all variables and given/known data
    People who are angry sometimes say that the feel as if they will explode. If a calm person with a lung capacity of 3.5L and a body temp of 36C gets angry, what will the volume of the persons lungs be if their temp rises to 39C.


    2. Relevant equations
    V1/T1 = v2/T2


    3. The attempt at a solution
    I did it like this:
    Declared variables; v1=3.5L, v2 = *?*, T1 = 36C, T2=39C

    put them into the formula; 39(3.5) = 36(V2)
    and ended up getting 3.79L instead of the correct answer which is 3.53L.

    Obviously I have zero idea of what I am doing if I get an answer wrong. Only answer if you understand what you're talking about. Thanks.

    When using gas laws, you should always use absolute temperature (temperature in kelvins)! Otherwise, the way you set up the calculation is correct.
