The Euken coefficient ξ is defined as ξ = (∂T/∂V)U. 

a. Show that the Euken factor is also equal to

{= T (OP/OT) - P Cv 

b. What is the value of the Euken coefficient for an ideal gas? 

c. Develop an explicit expression for the Euken coefficient for a gas that is described by the truncated virial equation

PV RT Z=1+ B(T) V

d. Develop an expression for the Euken coefficient for a gas that is described by the Peng-Robinson equation of state.
