    As I am reading the problem, i can tell the question gives you two temperatures, two pressures, one volume and asking for the other. this should be an indication that you need to use the following gas formula

    P1V1/T1 = P2V2/T2

    P1 = 2.0 atm

    V2 = 4.0 L

    T1 = 27 = 300 K

    P2 = 8.0 atm

    V2 = ?

    T2 = 327 = 600 k

    let's plug in the values into the formula

    (2.0 x 4.0) / 300 = (8.0 x V2) / 600 K

    V2 = 2.0 Liters

    answer is D
