On the other hand, the chemical nature of either material property becomes evident in the process of chemical reaction. In other words, it is possible to determine only the change by the chemical nature of the substance's quality. Chemical properties can not be determined only by observing or contacting substances, and the internal structure of the substances must be influenced by the chemical nature of the influence. Physical properties: The material has mass and volume, as indicated by the concrete block. You can have more than one to observe its quality when it tries to pick it up through its senses. You can look at it and be careful of its size to observe that volume. Quality and quantity are examples of a wide range of physical properties
The behavior and fate of chemicals in the environment depend on their chemical and physical properties and the nature of the environment. The chemical and physical properties are determined by the structure of the molecule and the nature of the atoms present in the molecule. These physical and chemical properties cover a wide range of values depending on the structure of the molecule. This compound can have very low sustainability, low toxicity and non-mobility. These compounds are unlikely to pose a danger to the environment and human health. The physicochemical properties, high lipid solubility, semi-volatility, and other properties of persistent organic pollutants such as low water solubility are the reasons for their behavior in the environment. Persistent organic pollutants have many physicochemical properties that can explain their behavior and their environmental impact.
