Physical performance:

Basic introduction: Refers to the properties of a substance that exhibit without undergoing a chemical reaction, which are called physical properties.

The physical properties of a substance, such as color, odor, state, susceptibility to melting, solidification, sublimation, volatilization, and other properties such as melting point, boiling point, hardness, conductivity, thermal conductivity, and ductility, can be measured using instruments.

There are also some properties that can be obtained through laboratory data and calculations, such as solubility, density, etc. These properties belong to physical properties.
