A) resistance to flow.
B) the rate of collisions for gas molecules.
C) the energy required to overcome the attractive forces between molecules in the liquid state to form a gas.
D) the force required to expand the surface of a liquid.
E) the drawing of a liquid up the inside of a small-bore tube when adhesive forces exceed cohesive forces.

Question

Quizplus · Accepted Answer

Capillary action refers to the drawing of a liquid up the inside of a small-bore tube due to the adhesive forces between the liquid and the tube being greater than the cohesive forces between the liquid molecules. This phenomenon is responsible for many important processes in nature, such as the movement of water through plants and the rise of blood in capillaries.
