Gas particles

Gas particles are tiny, individual units that make up gases. They move rapidly in all directions, colliding with each other and the walls of their container, which creates pressure. Unlike solids or liquids, gas particles are spread out and have a lot of empty space between them, allowing gases to expand and fill any container uniformly. Their behavior follows principles of physics that describe their speed, pressure, and temperature, such as the kinetic molecular theory. Overall, gas particles are small, fast-moving entities that determine the properties of gases like volume, pressure, and temperature.
