This thermodynamic quantity equals what?

  1. Mar 30, 2014 #1
    I am trying to use thermodynamics manipulations in order to find [itex]\partial[/itex]P/[itex]\partial[/itex]V (at constant entropy) I tried replacing P by T([itex]\partial[/itex]S/[itex]\partial[/itex]V)(at constant Energy) and then differentiated that by V but didn't help me. Do you have any idea where I can get around with this? Just throw in any formula!

    Well, there's ks = adiabatic compressibility (= reciprocal of the adiabatic bulk modulus):

    ks = - (1/v)(∂v/∂p)|s,
    s = sp. entropy.

    It's related to Cp/CV = γ = k/ks

    where k = the reciprocal of the isothermal bulk modulus = (-1/v)(∂v/∂p)|T.

    Made your day, eh? :tongue:
