A substance with a high amount of intermolecular forces will have a ______ vapour pressure.

Would a substance with a high vapour pressure have strong or weak intermolecular forces?

Capillary action is

• Caused by cohesive and adhesive forces

• Allows some liquids to 'flow' vertically up a thin tube

• Not observed in liquid mercury

• All of the above

Cohesive forces

• Are the attraction of molecules within a liquid

• Are the attraction of molecules to the container walls

• Are only present when the liquid is exposed to glue

• Are important for upward movement in capillary action
