Question

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

Select the correct option:

A

continuously lose their energy till it reaches wall.

B

are attracted by the walls of container.

C

continuously stick to the walls of container.

D

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

✓ Correct! Well done.

✗ Incorrect. Try again or view the solution.

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.
