Answer:
my term:
capillary movement (also known as capillarity, capillary motion, capillary effect, or wicking) is the tendency of a liquid to move through small spaces without the aid of, or even in contrast to, external forces such as gravity. Intermolecular forces between the liquid and the surrounding rigid surfaces trigger this.
original term:
Capillary action (sometimes capillarity, capillary motion, capillary effect, or wicking) is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity. ... It occurs because of intermolecular forces between the liquid and surrounding solid surfaces.
Hope it helps! Study well and don't pressure yourself :))
