Abstract
The nature of the pressure against density curve at constant temperature is investigated by the methods of the grand canonical ensemeble for a system of identical molecules between which only short range forces act. It is shown that, except for surface effects, the total energy, entropy, etc., are proportional to the number of molecules in the system. The pressure is proven to be a non-decreasing function of the density which may have regions of constancy as a function of the density. This shows rather clearly the impossibility for any analytic equation of the Van der Waals' type being able to give a satisfactory account of condensation without ad hoc assumptions.
