WebMatter is made up of extremely tiny particles called atoms and molecules. Atoms and molecules make up the three common states of matter on Earth—solids, liquids, and gases. The particles of a liquid are attracted to one another, are in motion, and are able to move past one another. Being a solid, liquid, or gas is a property of a substance. WebIntra molecular forces are those within the molecule that keep the molecule together, for example, the bonds between the atoms. Inter molecular forces are the attractions between molecules, which determine many of the physical properties of a substance. Figure 10.5 illustrates these different molecular forces.
