Capillarity vs Adhesion

Heya!

A level biology student here, what is the difference between capillarity + adhesion? I’m so confused

Thankyou!

Hello!

Capillary action is the movement of liquid due to adhesion, cohesion and tension; it’s what occurs as a result of these three factors.

Adhesion is one of these forces. If we look at it in the context of water moving in the xylem, adhesive forces are the hydrogen bonds formed between the water molecules and the wall of the xylem :smile:

Thankyou so much!! I was confused because a video said they were the same 😅
