write the postulates of kinetic molecular theory of gases
Answers
i) Gases consists of large number of tiny particles called molecules
ii) Gaseous molecules moving randomly in all directions with different velocities.
During their random motion they collide with each other and also with the walls of the container
iii) Collisions of gas molecules are perfectly elastic. their Total energy remains constant
iv) The actual volume of the gas molecules is negligible in comparison to the total volume of the container
v) Gases exert pressure due to the collision of the particles with the walls of the container
vi) There is no force of attraction between the particles of a gas at ordinary temperature and pressure
vii) Average kinetic energy of the gas molecules is directly proportional to the absolute temperature
