A gas exerts pressure on its container because
some of its molecules are moving faster than others
of the collision of the molecules with each other
of the mass of the molecules of gas
the molecules of a gas collide with the walls of the container
설명
A gas exerts pressure on the walls of the container as the particles of gas move randomly in all directions at high speed. As a result, the particles hit each other and also hit the walls of the container with force. However, gases exert pressure on their containers because the constant, random motion of gas molecules causes them to collide with the container walls, transferring momentum and resulting in a force, which is pressure.
