THEORIES ABOUT GAS

The kinetic theory of gasses is used to explain the behavior of gas molecules. It is the macroscopical study of gas molecules. The five postulates of the kinetic theory of gasses are as follows:

1) Gas is made up of a great amount of molecules that are continuously moving randomly.
2) Because the distance between the gas molecules is higher than the size of the molecules, the volume of the molecules is negligible.
3) The intermolecular interactions are also negligible.
4) The collision of molecules with each other and with the container's walls is always elastic.
5) The average kinetic energy of all the molecules is dependent on the temperature.
6) They have kinetic energy because of their mass and velocity
(K.E. = 1/2mv).
7) The molecules collide with one another and with the container's sides. Despite the transfer of energy from
one molecule to another, no kinetic energy is lost during collisions.
8) The molecule does not have the same kinetic energy at all times.
9) The molecule's average kinetic energy is directly proportional to its absolute temperature.
10) At any given temperature, the average kinetic energy of all gas molecules is the same
