      What is van der Waal's Equation?

      Equation of state for ideal gases (from the continuum theory) van der Waals’ Equation

      Equation of state for ideal gases (from the continuum theory)
      van der Waals’ Equation

      (p+(a/V(^2)(_m))·(V_m-b)=R·Τ

      a, b = constants (internal pressure, covolumes)
      Vm = Molar volume
