Capillary Action Hydrogen Bonding
Capillary action and hydrogen bonding
There are many kinds of things between heaven and earth, among which there are subtle reasons about capillary action and hydrogen bonding, which is the secret purpose of nature.
Watching capillary action is common in life. If a thin tube is inserted into the water, the water rises from the bottom up and climbs along the pipe wall, which is the manifestation of capillary action. The reason for this is the interaction between the surface tension of the liquid and the pipe wall. When the liquid comes into contact with the pipe wall, there is an attractive force between the liquid molecules and the pipe wall molecules. This attractive force prompts the liquid to extend along the pipe wall and then appear to rise.
And the hydrogen bond is a special force between molecules. Taking water as an example, water molecules are composed of hydrogen and oxygen, and hydrogen atoms and oxygen atoms are connected by covalent bonds. However, between different water molecules, hydrogen atoms and oxygen atoms of neighboring water molecules form a weaker interaction due to electronegativity differences, that is, hydrogen bonds. The existence of hydrogen bonds has a great impact on many properties of matter.
Due to hydrogen bonds, the boiling point of water is different from common sense. According to the molecular structure and relative molecular mass, the boiling point of water should be lower. However, due to the association of hydrogen bonds, water molecules need more energy to break free and turn into gaseous states, so the boiling point rises. And the density change of water is also related to hydrogen bonds. During the cooling process, the arrangement of water molecules becomes more regular due to hydrogen bonds, forming a tetrahedral structure, resulting in the density of ice being smaller than that of water. This is a natural wonder.
As for capillary action and hydrogen bonding, the two are also closely related. In capillary phenomenon, the interaction between liquid and pipe wall is partially due to the force of hydrogen bonding. If hydrogen bonds can be formed between liquid molecules and pipe wall molecules, the attractive force of the two will be enhanced, and the capillary rise will be more significant. The relationship between the two is reflected in many phenomena in nature and life. For example, plant roots absorb water, and they use the hydrogen bond force between capillary action and water molecules to transfer water from the roots to the branches and leaves, nourishing life.
The principles of nature are profound and infinite, and the capillary action and hydrogen bonds are subtle, but in one corner, it is also enough to see the miraculous and delicate creation of heaven and earth.
