KINETIC MOLECULAR THEORY:
The theory which explains the arrangement of particles in different states of matter according to the intermolecular forces of attraction and intermolecular distances, is termed as Kinetic Molecular Theory.
Introduction:
The gaseous state molecules are lying away from one another, this assumption was proposed by Boltzmann, Maxwell and Kelvin. They explain the behavior of gases according to kinetic Molecular Theory.
Kinetic Molecular Theory of Gases: Following are the points for the kinetic molecular theory of gases;
In gases, molecules are widely separated and far apart from one another along with free random motion due to weak intermolecular forces of attraction and greater intermolecular distances present between them.
Gas molecules travel in a straight line until they collide with one another and with the walls of the container and then start zigzag motion.
These collisions are totally elastic, it means there is no loss of energy.
The gas particles exert force around certain area on the walls of the container, which is known as “pressure”.
The average distance covered by gas particles during their successive collisions with one another and with the walls of the container, is termed as “mean free path”.
The particles of the gases possess average kinetic energy due to their motion.
(Kinetic energy) (Kinetic energy)
The average kinetic energy of the gas molecules is directly proportional to the absolute temperature.
(Kinetic energy) K.E ∝ Absolute Temperature
