Why is chemistry important in life?

Because chemistry allows you to recognize the world you live in. It can also make you understand that you can benefit mankind with good chemistry, but if you misuse chemical knowledge, you will destroy ourselves. Do you know why people who study chemistry don't pay much attention to what they eat?

Because they know that additives are everywhere.

This statement is quite perfunctory. No field can be made up of a single thing, that is, it can't be made without that object. The computer cup is important, the memory is important, the motherboard is important, and the power supply is also important.

Because it doesn't work without that, it's important. In life, it is important to be human, physical energy is important, aesthetic design is very important, and of course chemistry is also important. Because chemistry involves pharmaceuticals, industrial raw materials, catalysts, and a lot of biological research that needs to be detected or helped, chemistry is important.

Everything in life has chemicals, and water is no exception. If the substance has no chemicals, the substance is simply invisible.

To prevent aluminum poisoning, we should pay attention to (1) reduce the entrance route of aluminum, such as eating less sulfur dioxide is a very important member of inorganic chemical preservatives. Why does table salt deliquescent? How do you make it non-deliquescent? Often in table salt.

Life is inseparable from chemistry all the time. People's food, clothing, housing and transportation are inseparable from chemistry.

Everything in the world is made up of chemicals.

Chemistry is one of the important basic sciences, and it is an experiment-based discipline that is closely related to physics, biology, and geography.

In the interpenetration of astronomy and other disciplines, it has developed rapidly, and it has also promoted the development of other disciplines and technologies. For example, nucleic acids.

The results of chemical research have raised modern biology from the cellular level to the molecular level, and molecular biology has been established.

In addition, chemistry plays an important role in the understanding and utilization of substances. Different from particle physics and nuclear physics, which study smaller scales, chemistry studies elements, molecules, ions (clusters), and chemical bonds.

The basic properties are the microscopic natural laws that are most closely related to the matter and materials in the macrocosm of human existence.

The universe is composed of matter, and as an important bridge between the microcosm and macrocosm of the material world, chemistry is one of the main methods and means for human beings to understand and transform the material world. It is a discipline with a long history and full of vitality, which is very closely related to the progress of human beings and the development of society, and its achievements are an important symbol of social civilization.

From the beginning of the primitive society with fire.

To the modern society, where various man-made substances are used, humans are enjoying the fruits of chemistry. Human life can be continuously improved and improved, and the contribution of chemistry plays an important role in this.

The embryonic period of chemistry

From ancient times to 1500 B.C., human beings learned to make pottery from clay in a blazing fire, to burn metal from ore, to make wine from grain, and to dye silk and linen and other fabrics.

In ancient times, primitive humans discovered and used fire in the struggle against various disasters in the natural world for their survival. Primitive people began to use fire to enter civilization from barbarism, and at the same time, they also began to use chemical methods to understand and transform natural substances. Combustion is a chemical phenomenon.

After mastering fire, humans began to eat cooked food; Subsequently, humans have discovered some material changes, such as malachite, which was found in emerald green color.

When the copper ore is burned with charcoal, red copper will be generated. In China, the transformation of the Chunyan Zao and the Autumn Warring States period from a bronze society began, and the social changes caused by iron ox farming promoted the development of chemistry.

In this way, in the process of gradually understanding and using the changes in these substances, human beings have made products of great use value to human beings.

products. Human beings gradually learned to make pottery and smelt; Later, I learned about brewing, dyeing, and so on. These products, which are processed and transformed from natural substances, have become the hallmarks of ancient civilizations. On the basis of these production practices, ancient chemical knowledge was germinated.

1. Clothing: chemical fiber products alleviate the shortage of cotton, and even surpass chemical fiber in terms of performance.

2. Drugs: The synthesis of various medical drugs protects human health.

3. Food: water treatment to reduce diseases; Preserving, prolonging the shelf life of food.

4. Housing and transportation: the synthesis of various building materials to improve living conditions. Synthesis of transportation chemical raw materials such as automobiles to improve traffic conditions.

5. Leisure and entertainment: the development of various sports equipment materials, and the synthesis of various new entertainment materials.

Extended Information: The history of chemistry is very ancient, and it can be said that the earliest chemical practice began when humans learned to use fire. Our ancestors drilled wood to make fire, used fire to bake food, kept warm on cold nights, drove away wild beasts, and made full use of the glow and heat phenomenon when burning.

At the time, it was just an accumulation of experience. The formation of chemical knowledge and the development of chemistry have gone through a long and tortuous road. It develops along with the progress of human society and is the inevitable result of social development. And its development promotes the development of productive forces and the progress of history.

Experiments and theories have always been two aspects of chemistry research that are interdependent and mutually reinforcing.

Since the beginning of the 20th century, due to the influence of the development of other disciplines of natural sciences and the extensive application of contemporary scientific theories, technologies and methods, chemistry has made great progress in understanding the composition, structure, synthesis and testing of substances, and has made many important achievements in theory. On the basis of the four sub-disciplines of inorganic chemistry, analytical chemistry, organic chemistry and physical chemistry, a new sub-discipline of chemistry has emerged.

Since the 20th century, the development trend of chemistry can be summarized as follows: from macroscopic to microscopic, from qualitative to quantitative, from stable state to metastable state, from experience to theory, and then used to guide design and pioneering research. On the one hand, to provide as many new substances and materials as possible for the production and technical sectors; On the other hand, in the process of interpenetration with other natural sciences, new disciplines are constantly being created, and they are developing in the direction of exploring the life sciences and the origin of the universe.

As follows:

1. When pots and pans generate scale, you can remove scale by soaking it in vinegar.

2. When the fish bones are stuck in the throat, drink vinegar to soften the bones.

3. The principle of foam fire extinguisher is the application of chemical knowledge.

4. The ** of firecrackers also occurs after mixing some chemicals in a certain proportion and igniting them.

Chemistry is different from particle physics and nuclear physics, which study the material structure of atoms, molecules, ions (groups), chemical bonds, intermolecular forces and other interactions, and the scale in which they are located is the closest to the macroscopic in the microscopic world, so their natural laws are also most closely related to the physical and chemical properties of substances and materials in the macrocosm of human existence.

As an important bridge between the microscopic and macroscopic material worlds, chemistry is one of the main methods and means for human beings to understand and transform the material world.
