A Van der Waals force between molecules is a relatively weak intermolecular attraction. All neighboring molecules in liquids and solids attract each other. The nature and strength of these interactions depends on the types atom groups or functional...

Weak attractive forces acting between molecules. They are involved in the van der Waals equation of state for gases that compensates for the actual volume of the molecules and the forces acting between...

In chemistry and physics, the name van der Waals force is used as a synonym for the totality of intermolecular forces. These forces, which act between stable molecules, are weak compared to those appearing in chemical bonding. Historically, the use of...

IF CHEWING-GUM conformed to the simple laws of physics, it would not be very sticky. Unfortunately, as anyone who has ever struggled to get a piece of it off their shoe will have noticed, this is not the case. Gum is, in fact,...

Do atoms and molecules really exist? With our modem imaging techniques, which enable us virtually to 'see' atoms, such a question now seems superfluous. But before the relatively recent advent of such methods, chemists had to rely on other evidence. Some elementary textbooks...
