SUMMARY

The discussion focuses on the thermodynamic quantity of adiabatic compressibility (ks) and its relationship to other thermodynamic properties. The formula for ks is defined as ks = - (1/v)(∂v/∂p)|s, where s represents entropy. Additionally, the relationship between the heat capacities Cp and CV is established through the ratio γ = k/ks, with k being the reciprocal of the isothermal bulk modulus defined as k = (-1/v)(∂v/∂p)|T. These formulas are essential for understanding thermodynamic manipulations involving pressure and volume.

PREREQUISITES
  • Understanding of thermodynamic principles, particularly entropy and pressure relationships.
  • Familiarity with the concepts of adiabatic and isothermal processes.
  • Knowledge of bulk modulus and its significance in thermodynamics.

I am trying to use thermodynamics manipulations in order to find \partialP/\partialV (at constant entropy) I tried replacing P by T(\partialS/\partialV)(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!

Thanks!

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? :-p
