Kinetic Theory of Molecules
The kinetic theory of molecules describes the behavior of matter in terms of particles in motion. This theory makes these assumptions:
1. Gases are made up of particles with no defined volume but with a defined mass. In other words their volume is miniscule compared to the distance between themselves and other molecules.
2. Gas particles undergo no intermolecular attractions or repulsions. This assumption implies that the particles possess no potential energy and thus their total energy is simply equal to their kinetic energies.
3. Gas particles are in continuous, random motion.
4. Collisions between gas particles are completely elastic. In other words, there is no net loss or gain of kinetic energy when particles collide.
5. The average kinetic energy is the same for all gases at a given temperature, regardless of the identity of the gas. Furthermore, this kinetic energy is proportional to the absolute temperature of the gas.

Characteristics of a Solid

1. Solids particles are very tightly packed together.

2. Solids have a definite shape and volume.

3. Solids cannot be compressed.

4.

Q & A

Why do solids have a definite shape and volume?
Solids maintain a definite shape and volume because their particles
