Final answer:
Adhesion is the attraction of water molecules to other substances, enabling processes like capillary action where water defies gravity and moves through narrow spaces, as seen in plant water transport.
Step-by-step explanation:
Adhesion refers to the property of water that causes water molecules to stick, or adhere, to other molecules. This property of water is what allows water to defy gravity through a process known as capillary action. An example of this is when water climbs up the inside of a straw placed in a glass of water. The water molecules create hydrogen bonds with the surface of the straw, which makes the water adhere to the straw's sides. As these bonds continually form and break, water is able to move upward against gravity. Capillary action is crucial for the survival of many organisms as it facilitates the transport of water from the roots to the leaves in plants.
Adhesion is the attraction between water molecules and other molecules. It occurs when water molecules are attracted to the surface of another substance and adhere to it. This property is important for capillary action, which allows water to flow against gravity in narrow spaces, such as when water climbs up a straw or the sides of a capillary tube.
