WebFor instance, adhesion enables water to “climb” upwards through thin glass tubes (called capillary tubes) placed in a beaker of water. This upward motion against gravity, known as capillary action , depends on the attraction between water molecules and the glass walls of the tube (adhesion), as well as on interactions between water molecules (cohesion). WebThe greater the velocity of the water, the greater the flow rate of the river. But flow rate also depends on the size of the river.
