How do gas particles generally move?

Gas particles are characterized by their random and rapid motion. They move in all directions, which is a fundamental property of gases. This random movement occurs because gas particles have a significant amount of energy, allowing them to collide with each other and with the walls of their container.

This explanation aligns well with the kinetic molecular theory, which states that gas particles are in constant motion and that this motion is independent of the motion of other particles. As a result, the distribution of gas particles can be uniform throughout the available space, leading to the ability of gases to fill their containers completely.

The other options imply constraints on the movement of gas particles. Circular motions or movement only towards walls would limit the free motion characteristic of gases, which is not representative of how gas particles behave in reality. Thus, the correct understanding of gas behavior reinforces that these particles indeed move in all directions.
