Critical behavior at the liquid-gas critical point


Use the Van der Waals equation to calculate the critical behavior of:


1) the specific heat ,


2) the isothermal compressibility , and


3) the reduced density jump (across the first order transition line).


Determine the corresponding critical exponents.
