How do gas particles generally move?

Gas particles generally move in all directions, which is consistent with the behavior of gases in accordance with the kinetic molecular theory. This theory posits that gas particles are in constant random motion and they collide with one another and with the walls of their container.

This random movement is a result of the energy possessed by the particles, which allows them to move freely without any fixed pattern. Because of this inherent nature, gas particles fill any available space, traveling in various directions. This characteristic is essential for understanding various phenomena, such as gas pressure and diffusion, as the particles exert pressure on the walls of the container and spread out to fill the available volume.

The other options suggest limitations or specific conditions in the movement of gas particles. For instance, the idea of gas particles moving only in straight lines or exclusively toward the walls of the container does not accurately represent the randomness and freedom of movement characteristic of gas. Similarly, the notion of circular patterns does not apply, as gas particles do not exhibit systematic circular motion in an unrestricted environment.
