what are the postulate of kinetic theory of gases ?
Answers
Kinetic theory is based on the kinetic energy of moving particles. The kinetic energy is directly related to the temperature. In Boyle's Law the temperature is helped constant, so the kinetic energy of the molecules is a constant. The pressure and the volume are inversely related in Boyle's Law.
Answer:
Gases consist of a large number of tiny particles (atoms and molecules). These particles are extremely small compared to the distance between the particles. The size of the individual particle is considered negligible and most of the volume occupied by the gas is empty space.
These molecules are in constant random motion which results in colliding with each other and with the walls of the container. These collisions with the walls cause the pressure exerted by the gas.
The collisions between the molecules and with the walls are perfectly elastic. That means when the molecules collide they do not lose kinetic energy. Molecules never slow down and will stay at the same speed.
The average kinetic energy of the gas particles changes with temperature. i.e., The higher the temperature, the higher the average kinetic energy of the gas.
The molecules do not exert any force of attraction or repulsion on one another except during collisions.
