Answers
A is the answer
For example, water molecules in the bulk liquid are subjected to uniform cohesive forces whereby hydrogen bonds are formed with neighboring molecules on all sides. In contrast, molecules at the air–water interface experience net attraction into the liquid because of lower density of water molecules on the air side of the interface, with most hydrogen bonds formed at the liquid side.
Capillary rise of water
(a) depends on the force responsible.
Capillary action is a significant capacity of water to go through other materials. Water is not the only liquid that can do this, but its properties improve capillary action compared to most other substances.
If you put a narrow straw in a glass of water, what can you see about the level of water in the straw compared to the glass? You should see that the water has climbed to straw and glass is higher than the water level. It seems that gravity has been violated by taking the straw upwards. This is the capillary verb - movement of the liquid through or through the surface of any other material in spite of other forces like gravity.
Capillary action is the property seen in some liquids. It is the most obvious in water due to the unique properties of water, and because water is the basis of most liquid substances that use every liquid. When you use a paper towel to cover a soft drink or use a towel to dry itself after bath, you are using capillary action. When you cut flowers in the water vase, the capillary action keeps them fresh.
Better than most fluids, water is good in capillary action. How well the achievement of a liquid capillary action can be depends on solidarity and adhesion. The combination is the attraction between particles of the same type. There is strong solidarity in water. A water molecule strongly attracts the other. The adhesive is the attraction between two different particles. Adhesive between water molecules and plastic straws is also strong.
Capillary action occurs when the adhesive strength is greater than the combined strengths. Although water molecules are strongly attracted to each other, they are attracted to straw plastic. The result is that water molecules will climb on the surface of the straw of the straw and the level of water will be slightly higher within the straw. There is also better adhesion between water and glass. If you had a glass straw similar to the plastic straw, then you would see an increase in water level and even more.
So why does not water climb on the edges of glass, you can ask? It does, but only a little bit. The larger the ship, the united forces will end between water molecules and stop the water from climbing the glass edges. Collapse vessel or tube, more effect of capillary action
