Question

Collisions between the molecules of a gas and its container exert pressure on the walls of the container.

• A. True
• B. False

Answer 1

The correct option is A True

The pressure exerted by a gas on the walls of a container can be explained by the simple kinetic theory of gases.

• The molecules of gases generally possess high kinetic energy and negligible force of attraction therefore, they are moving constantly with high speed in all directions.
• This random motion of particles will result in their collision with each other and with a wall of the container.
• This results in the exertion of pressure on the walls of the container.

Thus, the given statement is true.
