On the basis of kinetic theory of gases, the gas exerts pressure because its molecules:

Options

  1. Acontinuously stick to the walls of container.
  2. Bsuffer change in momentum when impinge on the walls of container.
  3. Ccontinuously lose their energy till it reaches wall.
  4. Dare attracted by the walls of container.

Correct answer

B. suffer change in momentum when impinge on the walls of container.

Step-by-step solution

From the assumption of KTG, the molecules of gas collide with the walls and suffers momentum change which results in force on the wall and hence pressure.
