Nettetvan der Waals gas (and liquid) at the phase transition are examined in two different limit approximations. The ﬁrst limit approximation is at the near-critical temperatures, i.e., for T/Tc → 1, where Tc is the critical temperature, the other limit approximation is at the near-zero temperatures, T → 0. In these limits, the analytical ...

They differ from covalent and ionic bonding in that they are caused by correlations in the fluctuating polarizations of nearby particles (a consequence of quantum dynamics [6] ). paying a foreign employee

"NettetIn the Van der Waals equation, the second virial coefficient has roughly the correct behavior, as it decreases monotonically when the temperature is lowered. The third and higher virial coefficients are independent of temperature, and are not correct, especially at low temperatures. " - Limitations of van der waals equation
