What are its physical properties?
What are the physical properties of a substance? This needs to be explored in detail.
The physical properties of a substance involve a wide range of aspects, the first being form. Or it is a solid state, with a solid texture and a fixed shape and volume, like gold and stone, which stands firmly in the world and is not easily moved by external forces; or it is a liquid state, which flows freely and changes with the shape of the container, like the agility of water, which can meander in a ditch; or it is a gaseous state, which is ethereal and invisible, filling space, unrestrained, like a breeze, which is hard to find.
Secondary and color, colorful, red like fire, passionate and unrestrained; blue like the deep sea, deep and mysterious; white like frost and snow, pure and flawless. This is the intuitive representation of matter, which is clear at a glance.
Furthermore, density is also the key. The heavy sink, the light float, the iron stone sinks due to high density, and the wood bamboo floats due to low density. This is the law of nature.
As for the melting point and boiling point, it is related to the transformation of material form. When heated, it melts, reaching the boiling point and gas, ice melts in the warm sun, and water boils in the fire. These are all manifestations of physical properties.
It has hardness, either hard or soft. Diamond is strong and can scratch gold; silk is soft and smooth to the touch.
It is also conductive. Metals are very good at conducting electricity, which can make current flow freely, while rubber and the like are insulating and can block the passage of current.
Looking at the physical properties of matter, such as looking at the world, each has its own wonders and intertwined, forming a rich and colorful world in which we live. Only by carefully exploring can we understand its mysteries.
What are the precautions during the preparation process?
In the process of making utensils, there are many things to pay attention to, which are related to the formation and quality of the utensils.
First, the selection of materials is the key. "Kaogong Ji" says: "There are times in the sky, the earth has gas, the materials are beautiful, and the workmanship is clever. Combine these four, and then you can be good." The time and gas are different, and the material properties are different. The selection of materials should be based on the weather and the earth, and the material is beautiful. If you cast a sword, you need to choose high-quality iron, which is tough and pure in texture, so that the blade can be sharp and durable. If there are flaws in the material, even if you are exquisite, it is difficult to make a good tool.
Second, exquisite skills are indispensable. The craftsman needs to be familiar with various techniques, such as the splicing of mortise and tenon in woodworking, which requires extremely high accuracy. The mortise and tenon fit properly, and the wood can be firm and durable. Another example is ceramic firing, fire control is extremely important. The size and duration of the fire affect the color and quality of the ceramic. Before the fire arrives, the pottery is loose; if the heat is too high, the utensils are easy to crack. Therefore, craftsmen need years and months of experience to be able to accurately control.
Third, the design concept cannot be ignored. The utensils not only need to be practical, but also aesthetic. Many ancient utensils, such as the bronzes of the Shang and Zhou Dynasties, have exquisite shapes and complex patterns, which have both practical and artistic value. When designing, it is necessary to consider the use of the utensils and the preferences of the audience, so that the shapes and patterns complement each other.
Fourth, the production process needs to be rigorous. From the first blank to the finished product, every step must be meticulous. For example, the production of lacquer ware, from tire making, painting to decoration, there are many processes. If a certain link is negligent in the middle, such as uneven painting, or pattern loss during decoration, it will affect the overall quality of the utensils.
The making of utensils is a complex and delicate matter. Material selection, skills, design, process and other aspects need to be carefully considered and treated before they can become fine utensils.
What are the common types of reactions in chemical reactions?
Chemists explore the study of material change. In chemical reactions, there are many common types of reactions.
One is a combination reaction. This is a reaction in which two or more substances combine to produce a new substance. For example, hydrogen and oxygen, when burned, combine into water, and the formula is: $2H_ {2} + O_ {2}\ stackrel {ignite }{=\!=\!=} {2} O $. In this reaction, hydrogen and oxygen combine to form a new substance of water.
The second is a decomposition reaction. Contrary to synthesis, it is a reaction in which one substance decomposes to produce two or more other substances. Taking the electric decomposition of water as an example, water is decomposed into hydrogen and oxygen by the action of electric current, and the formula is: $2H_ {2} O\ stackrel {energized }{=\!=\!=} 2H_ {2}\ uparrow + O_ {2}\ uparrow $. The original single water, through this reaction, splits into hydrogen and oxygen.
The third is the displacement reaction. In this reaction, an elemental substance interacts with a compound, and the elemental substance replaces an element in the compound to form a new elemental substance and a new compound. For example, in the reaction of iron and copper sulfate solution, iron replaces the copper in copper sulfate and becomes ferrous sulfate itself, which is: $Fe + CuSO_ {4 }=\!=\! = FeSO_ {4} + Cu $. Iron is an elemental substance, and copper sulfate is a compound. After the reaction, the copper elemental substance and the ferrous sulfate compound are obtained.
The fourth is a metathesis reaction. This is a reaction in which two compounds exchange components with each other to form two new compounds. It usually occurs in solution, and the product must have precipitation, gas or water to form before the reaction can be completed. If hydrochloric acid reacts with sodium hydroxide to form sodium chloride and water, its formula is: $HCl + Na O H =\!=\!= NaCl + H_ {2} O $. Hydrochloric acid and sodium hydroxide exchange components to obtain a new compound sodium chloride and water.
These four are common types of reactions in chemical changes, and play a crucial role in chemical research and practical applications.
What is the environmental impact of this compound?
The impact of today's harmonious things on the environment is quite important. Although "Tiangong Kaiwu" does not discuss in detail the term "environmental impact", the production and use of the objects involved also contain this meaning.
Viewed from the perspective of the creation of ceramics, the selection of soil materials requires a specific place. The soil nature and texture of this place are related to the quality of ceramics. This choice of land has a real impact on the surrounding environment. If you over-exploit a piece of soil, you may cause changes in the topography of the land, damage to the soil structure, affect the vegetation, or cause soil erosion.
When smelting metals, the fuel consumption is huge. Charcoal is often used for burning, a large number of trees are cut down to make charcoal, and the vegetation of mountain forests is suddenly reduced. There are few mountains and forests, and their ability to conserve water and protect soil and regulate climate is also weak. And during the smelting process, smoke rises, containing impurities and dust, dispersing in the air, causing air quality to decline, and the breathing and life of surrounding residents are disturbed.
In the papermaking industry, a lot of water is required for leaching raw materials, cooking and other processes. If wastewater is not properly treated and discharged directly, the water quality of nearby rivers will be polluted, the habitat of aquatic organisms will be damaged, or fish and shrimp will be reduced, and aquatic plants will wither. And the raw materials required for papermaking are mostly bamboo, hemp and other plants, which are overused, which is harmful to the reproduction of plant populations and destroys the ecological balance.
The pigments used for dyeing may contain harmful substances such as heavy metals. During the dyeing process, wastewater flows into the environment, polluting soil and water sources. Over time, the fertility of the surrounding land decreases, the growth of crops is inhibited, and the health of people who eat such agricultural products is also at risk.
To sum up, it can be seen that when the chemical is used in production and use, although it is used by people and convenient for life, it also damages the environment. Future generations, when they use it, they will think carefully and find ways to protect the safety of the environment and ecological balance.
