What is the kinetic theory of gases and how can it explain some of the gas experiments?
- It is the study of behavious of molecules.
- Gases consist of molecules or atoms in continuous random motion.
- Collisions between these molecules and/or atoms in a gas are elastic.
- The colume occupied by the atoms and/or molecules in a gas in negligibly small.
- The attractive or repulsive forces between the atoms and/or molecules in a gas are negligible.
- The average kinetic energy of a molecule or atom in a gas is directly proportional to the kelvin temperature of the gas.
- Molecules collides with the wall of the container and also with each other, collisions with the wall account for the pressure of the gas.
- There are no repulsion or attractive force between the molecules except during collision.
Kinetic particle theory of gases states that all gaseous particles are in constant, random motion and are make up of discrete, tiny particles. This tells us about the properties of gases, whether it is about its fixed shape or volume or its high speed.
Kinetic theory of gases, describes the nature of all gases in terms of random movement of the molecules that constitute the gas, and explains how such movement of molecules at high speed determines temperature, pressure and other properties of gases.
