Answer 2

Physisorption is the physical bonding of gas molecules to the surface of a solid or liquid that the gas comes into contact with at low temperatures. This occurs due to Van der Waals forces. The weak, long-range bonding is not surface specific and takes place between all gas molecules on any surface.
