On the basis of kinetic theory of gases, the gas exerts pressure because its molecules:
Options
- Acontinuously stick to the walls of container.
- Bsuffer change in momentum when impinge on the walls of container.
- Ccontinuously lose their energy till it reaches wall.
- 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.
