mao dẫn
Definition
- Noun:
- Capillarity: The physical phenomenon where a liquid spontaneously rises or falls in a narrow tube, porous material, or fine space due to the interplay between cohesive forces within the liquid and adhesive forces between the liquid and the solid surface.
- Capillary action: The process itself, which is responsible for liquid movement in small spaces against gravity, such as water moving up a plant's roots or through a paper towel.
