Question

Gases exert pressure on the walls of the container because
the gas molecules
(a) possess momentum
(b) collide with each other
(c) have finite volume
(d) obey gas laws.

Answer 1

Answer:

Pressure exerted by the gas molecules on the walls of container is calculated by the no. of collisions on the wall.

What a collision on the wall do is they apply a force on the wall due to the change in momentum of molecules.

⇒ Pressure =

Area

force

=

Adt

dP

Where dP is change in momentum.

Hence, the answer is Possess momentum.

Answer 2

Answer:

Gases exert pressure on the walls of the container because the gas molecules collide with each other .
