Capillary Action
Capillary Action
Height of water in capillary tube
- Capillary action is due to both adhesion and cohesion.
- For capillary action, diameter of tube should be less than 3 cm.
- Tubes of manometers are taken more than 6 mm in diameter in order to avoid the correction due to capillarity, because with increase in capillary diameter rise/fall decreases.
