Attempt $4$

$$ Pressure is the average force with which gas molecules hit the walls of the containers. Conceptually we broke pressure into how "hard" the particles hit the wall and how often. Let us translate this to physics. The force with which the gas particles hit the wall is actually proportional to the change in the momentum, or $mv.$ The change refers to the momentum after the collision the wall is the change in the direction of the motion of the particle. Therefore the force is proportional to ms $-$ the mass x speed.

Use this idea, that Pressure propms, to select the correct statement$($s$)$ below. There may be more than one.

In a container of the same gases, the gas particles with the higher speeds exert greater forces on the walls of the container.

When a particle hits the wall its mass does not change.

In a container of different gases, the gas particles with the higher speeds exert greater forces on the walls of the container.

When a particle hits the wall its speed does not change.

Two particles that hit the wall cannot possibly have the same momentum.
