Homework Help: Which gas is more compressible

  1. Nov 26, 2017 #1
    1. The problem statement, all variables and given/known data
    Gas A at 125KPa (abs) is compressed isothermally and gas B at 100kPa(abs) is compressed isentropically (Y = 1.4). Which gas is more compressible?

    2. Relevant equations
    Compressibilty = 1/bulk's modulus
    Bulk's modulus = F/A/V/v or volume stress/volume strain

    3. The attempt at a solution
    I'm not sure I'm using the right equation , ive also tried Q= w(Y-n)/(y-1), but for an adiabatic compression Q is always 0, so does that mean the isothermally compressed gas is more compressible??
