What Are Van Der Waals Forces
Van der Waals forces relatively weak electric forces that attract neutral molecules to one another in gases in liquefied and solidified gases and in almost all organic liquids and solids. These forces determine whether a substance is a solid liquid or gas at a given temperature. Van Der Waals Forces Periodic Table Ios App Chemistry Periodic Table Interactive They are names after the Dutch chemist Johannes van der Waals 1837-1923. . The reason for the clean interfaces is the van der Waals forces that attract adjacent crystals and effectively squeeze out trapped contaminants or force them into micrometre-sized bubbles 16. In chemistry and thermodynamics the Van der Waals equation or Van der Waals equation of state is an equation of state which extends the ideal gas law to include the effects of interaction between molecules of a gas as well as accounting for the finite size of the molecules. The forces are named for the Dutch physicist Johan
