The properties of matter areThe properties of a substance referred to the characteristics and properties of the substance. It could be divided into physical properties and chemical properties.
Physical attributes included color, shape, texture, density, melting point, boiling point, and so on. These could be measured by senses or instruments. For example, the color and shape of a substance could be determined by observation, and the density of a substance could be measured by instruments.
The chemical properties included chemical reaction, acid and base properties, and oxidization. It described the ability of a substance to undergo chemical changes with other substances.
In addition, from a philosophical point of view, motion was the essential attribute of matter. There was no matter in the world that did not move, and time and space were the forms of existence of moving matter. At the same time, mass was also the fundamental property of matter. It was dependent on motion, and mass had two fundamental properties: inertia and disturbance to space-time. The law of the properties of matter states that the basic properties of matter are not affected by pure mechanical motion (when there are no other external factors).
In different research fields, the manifestation of material attributes was also different. For example, in the brand category, the material attributes of the brand determined the function of the product. In the study of people, people also had corresponding material attributes when they existed as a material. Material properties determined the behavior and use of materials under different conditions, which was of great significance in scientific research and engineering applications.
The properties of tertiary cementiteIn most types of steel, tertiary crystallizer has little effect on the performance, but in low carbon steel, its appearance may reduce the toughness a lot, affecting stamping, cold heading and other processing. When the tertiary crystallizer appeared in the alloy spherical iron, the comprehensive mechanical properties of the casting would deteriorate.

The eight physical properties of matterThere were many ways to classify the physical properties of matter. There were no clear eight physical properties, but the common physical properties included density, specific heat capacity, hardness, clarity, electrical conductivity, thermal conductivity, elasticity, magnetism, and so on.
The density was the ratio of mass to volume. Different substances generally had different density and could be used to identify substances. The specific heat capacity reflects the ability of a substance to absorb or release heat. Hardness reflected the ability of a material to resist external invasion. The degree of clarity indicated the degree to which the material allowed light to pass through. Conductivity reflected the ability of a substance to conduct electricity. Heat conductivity is the ability of a substance to conduct heat. Elasticness refers to the property of an object that is deformed under the effect of an external force. When the external force is removed, it can return to its original shape. Magnetism was the ability of a substance to attract iron, tungsten, and other substances.
