All of the following statements are consistent with the kinetic molecular theory of gases EXCEPT:
A. The gas molecules collide with each other and with the surfaces around them.
B. Strong attractive forces hold the gas molecules together.
C. The average kinetic energy of the molecules of a gas is proportional to the temperature of the gas in kelvins.
D. The size of the gas molecules is negligible compared to the total volume of the gas.
E. none of the above.

Respuesta :

Answer:

B. Strong attractive forces hold the gas molecules together.

Explanation:

Kinetic molecular theory postulates:-

  • The gas is composed of small molecules are they are in continuous random motion and having elastic collisions with one another and also with the walls of the container.
  • The molecules of the gas does not exert any kind of repulsive or attractive forces on each other and they their size is negligible as compared to the difference between them.
  • Pressure exerted by the molecules of the gas results from the collisions which is happening between the molecules of the gas and the walls of the container.
  • Average kinetic energy of molecules of the gas is directly proportional to absolute temperature.

Hence, The correct option which is not a postulate of kinetic molecular theory is:- B. Strong attractive forces hold the gas molecules together.
