Homework Help: Thermodynamics alegbra problem

  1. Apr 4, 2013 #1
    1. The problem statement, all variables and given/known data

    i solved for H=N1Cv1(Tf-T1)+V1(Pf-P1)+N2Cv2(Tf-T2)+V2(Pf-P2)

    my TA says that i have to simplify this, i dont really see a good way to go about it

    2. Relevant equations

    Pf=(Tf/T1)P1 Pf=(Tf/T2)P2

    3. The attempt at a solution

    I think you could use the ideal gas law to get rid of the pV terms.

    so since PV=NkbT

    H=N1Cv1(Tf-T1)+N1kb(Tf-T1)+N2Cv2(Tf-T2)+N2kb(Tf-T2)

    is there a relationship between kb and Cv?
