Dear all, is the relation between chemical composition of a material and its physical properties a peering relation or a relation of subordination?

xhtp2000 said:nope, it's about my PhD project, we are now starting sorting of the recycled materials based on chemical composition, the traditional sorting criteria is mostly based on the physical and mechanical properties, I am thinking of the relation of this hierarchy, and wondering why is a new sorting criteria advantageous or specific over others.
Chemical composition refers to the types and amounts of elements that make up a substance. It is the ratio of elements in a substance that determine its chemical properties.
The chemical composition of a substance determines its physical properties, such as melting point, boiling point, density, and color. This is because the arrangement and strength of chemical bonds between elements affect how the substance interacts with its environment.
One example is how the ratio of carbon and hydrogen in a molecule determines whether a substance is a gas, liquid, or solid at room temperature. Another example is how the presence of certain elements in a compound can make it more or less reactive with other substances.
Yes, substances with the same chemical composition can have different physical properties if they have different arrangements of atoms or different types of bonds between them. For example, carbon can exist as diamond, graphite, or coal, all with different physical properties despite having the same chemical composition.
Scientists use various techniques such as spectroscopy, x-ray diffraction, and chromatography to analyze the chemical composition of a substance and observe its physical properties. They can also conduct experiments to study how changes in chemical composition affect physical properties.
