Question

The Kinetic Molecular Theory describes the behavior as well as the characteristics of an ideal gas. What are the five postulates of this theory? Provide at least 3 examples to describe these postulates.

Answer 1

See explanation

Step-by-step explanation:

The postulates of the kinetic theory of matter are;

1. Every substance is made up of tiny particles called molecules. Brownian motion and diffusion illustrates this fact.
2. The molecules that compose matter are in constant random motion.
3. There exists an attractive force between the molecules in matter. The attractive forces between gases are negligible. Solids have a definite shape and volume due to a high magnitude of intermolecular forces. Liquids have a volume but no definite shape due to weaker intermolecular forces. Gases have the weakest intermolecular forces hence the do not have both a shape and volume. They take on the volume of the container into which they are put. This illustrates this fact.
4. The actual volume occupied by gas molecules is negligible relative to the volume of the container. The fact that gases are easily compressible illustrates this fact.
5. Temperature is a measure of the average kinetic energy of the molecules of a body.
