Kinetic theory

  1. Mar 29, 2007 #1
    1. The problem statement, all variables and given/known data

    A certain mass of a diatomic gas (gamma=1.4) occupies a volume of 100 cm^3 at a pressure of 75 cm of Hg. It is compreseed adiabatically until the pressure increases to 80 cm of Hg. Calculate the workdone in the process.

    2. Relevant equations

    W=1/(gamma -1)* (p1v1-p2v2)
    where gamma=cp/cv
    cp=molar specific heat of the gas at constant pressure
    cv=molar specific heat of the gas at constant volume.

    3. The attempt at a solution

    i tried the formula and got -10 J but the correct answer is 29.2 J and i dont have a clue of the method.
