gasesthat is a term that refers to substances in a gaseous state. Gases are one of the fundamental states of matter, characterized by their ability to expand and fill any container they occupy. Unlike solids and liquids, gas particles are far apart and move randomly at high speeds. This molecular behavior leads to several key properties of gases.

Gases are compressible, meaning their volume can be significantly reduced by applying pressure. They also exert pressure in all directions due to the constant motion and collisions of their particles with the walls of their container. Diffusion is another characteristic property, where gases will spontaneously mix with other gases. The rate of diffusion depends on factors like temperature and the mass of the gas particles.

Common examples of gases include oxygen, nitrogen, and carbon dioxide, which are essential for life on Earth. Other notable gases include helium, used in balloons, and hydrogen, a potential fuel source. The behavior of gases can be described by gas laws such as the ideal gas law, which relates pressure, volume, temperature, and the amount of gas. Understanding gases is crucial in various scientific and industrial applications, from atmospheric science to chemical engineering.
