Capillary action is the phenomenon where water climbs up a straw due to adhesion to the straw's surface, pulling the water along with it. This occurs because the adhesive forces between water and the straw are stronger than the cohesive forces within the water molecules.
Adhesion is when water molecules stick to other molecules
This force is called adhesion and is the attraction between molecules of different substances. Adhesion is important in everyday phenomena such as water sticking to glass or a gecko sticking to a wall.

The combined force of attraction among water molecules and with the molecules of surrounding materials is called adhesion.
When the balloon is filled with water, it creates pressure on the water inside the straw, causing the water level in the straw to rise. When the balloon is squeezed, the pressure is increased, causing the water level in the straw to rise even further due to the increased force.
Surface tension is related to the cohesive properties of water. Capillary action however, is related to the adhesive properties of water. You can see capillary action 'in action' by placing a straw into a glass of water. The water 'climbs' up the straw. What is happening is that the water molecules are attracted to the straw molecules. When one water molecule moves closer to a the straw molecules the other water molecules (which are cohesively attracted to that water molecule) also move up into the straw. Capillary action is limited by gravity and the size of the straw. The thinner the straw or tube the higher up capillary action will pull the water.
cohesion and adhesion
Adhesion is when water molecules stick to other molecules
It is still called water. The phenomenon that it's demonstrating is called capillary action.
Becouse of its strong dipole and hydrgen bonds. Water has a property of cohesion and adhesion so it sticks to itself yet climbs the tree using adhesion. Although, in the lab water cannot be replicated to climb as high as trees such as redwoods and even smaller trees like pines. The most it can climb in lab is 23ft. It is still a mystery.
The bending of the straw in a glass of water is due to refraction of light. When light passes from air into water, it changes speed and direction, causing the apparent bending of the straw. This phenomenon is called refraction.
When water is attracted to water it is called cohesion. When water is attracted to other materials, it is called adhesion. This occurs because water is polar.
An attraction between substances of the same kind is called cohesion. However, if it occurs in water, then it is known as capillary action.
When water is attracted to other water molecules it is called cohesion. When water is attracted to other substances it is called adhesion.
The above property of water is called anomalus
adhesion - when different molecules stick together (water to clothes) cohesion - when molecules of the same type stick together (water to water)
Transporting water molecules up high in tall trees is done with cohesion along with adhesion of water creating a column of water in the xylem(tube) of trees helping push it upward to the leaves up high. This is helped by evaporation.
