What is capillary action and when does it happen?
a. Capillary action is the ability for a tube to draw liquid into via the adhesive force. It occurs when adhesion is greater than cohesion, causing water molecules to attract to tree tissue.
b. Capillary action is the ability for a tube to release liquid via cohesion. It occurs when cohesion is greater than adhesion, causing water molecules to attract to tree tissue.
a. Capillary action is the ability for a tube to draw liquid into via the adhesive force. It occurs when adhesion is greater than cohesion, causing water molecules to attract to tree tissue.
