Question

Explain how capillary action occurs.

Accepted Answer

Capillary action:Example: transpirationOne H2O molecule gets pulled up because of the adhesion of water to the walls of a vesselThis pulls H2O molecules which are below it, upwards due to cohesion between H2O molecules, causing a continuous stream This means that there is a net movement upwards, against gravity
