Why is it experimentally difficult to accurately find the critical volume of a real gas?
I was reading up on the derivation of the values of various critical state functions( $\ce{Vc}$, $\ce{pc}$ and $\ce{Tc}$) from the Van der Waals equation (Physical Chemistry by G.W. Castellan). There, ...

Why is Inversion Temperature not equal to Boyle's temperature?(Theoretically)
Mathematically, it is proven that the inversion temperature is twice that of Boyle's temperature.
But if a gas is not showing the Joule-Thompson effect, it is behaving ideally and it has no ...

How should I evaluate $\left(\frac{\partial U}{\partial V}\right)_T$ with van der waals equation: $P = \frac{nRT}{V-nb}-a(\frac{n}{V})^2$?
So in my homework I was able to get this-
$\left(\frac{\partial U}{\partial V}\right)_T = T(\frac{\partial P}{\partial T})_V - P$
but now I'm trying to plug in $P = \frac{nRT}{V-nb}-a(\frac{n}{V})^2$ ...

What is the value of isothermal compressibility of a van der Waals gas at critical point?
For a van der Waals gas, isothermal compressibility is $$\kappa=\frac{V^2(V-nb)^2}{nRTV^3-2an^2(V-nb)^2}$$ If one substitutes the values of critical temperature and volume in this formula, isothermal ...
