Erroneous specific heat
I am modeling argon as a monatomic gas. (3 translational dofs). I select the kinetic theory option for specific heat and set the number of dofs to 3.
Cv should then be based on a formula like (f/2)kT and be 3.12 J/kg/K
Cp should be based on the formula (f+2)/2 kT and be 520 J/kg/K
where f is the number of dofs.
However, when Cp is plotted it returns the value 312.
Only by setting f=5 can the correct Cp be obtained
