Document Summary
Textbook notes, chapter 8, sections 8. 2, 8. 7, 8. 9, According to the theory, a gas consists of tiny molecules in constant, rapid, random motion. 5 fundamental postulates make up the foundation of the kinetic molecular theory. A gas is composed of molecules whose size is much smaller than the distances between them. This explains why gases can easily be compressed, since there must be much unoccupied space in gases that provide a lot of room for additional molecules in a sample of gas. Gas molecules move randomly at various speeds and in every possible direction. Gases quickly and completely fill any container in which they are placed. Except when gas molecules collide, forces of attraction and repulsion between them are negligible; collisions with molecules in the walls of a solid container account for gas pressure. Consistent with the fact that all gases behave the same way, regardless of the types of noncovalent interactions among their molecules.
