Anything that has a density, the space it occupies, which we experience by one or more senses, is called Matter. That is, in other words, we can say that matter is the object that surrounds a place, which has a fixed mass. Which can exert pressure, produce physical resistance, and whose existence can be experienced by our senses. Substances in the physical structure depend entirely on the molecular {intermolecular} forces present between their molecules. The size and volume of a substance in a solid are both fixed because the attraction force between the molecules and the intermolecular forces are stronger than the forces of their separation. Let's test your knowledge about Metal and Their Properties.
