Question

Give reasons for the following.

Gases exert pressure on the walls of container.

Answer 1

• The particles of a gas are in constant random motion at high speed.
• This random motion results in the collisions of particles among themselves and with walls of the container.
• $Pressure=\frac{Force}{Area}$
• When these randomly moving particles collide with the walls of the container, they exert a force per unit area on the wall of container resulting in pressure.
