What is Van Der Waals equation and how does it account for real gases?
What is [P + (an^2)/(v^2)] (V-nb) = nRT, accounts for behaviors seen at high pressures and low temperatures. At really high pressures particles begin exhibiting attractive forces, at really low temperatures particles begin condensing and exhibiting their own volume.
