gási

Gási, also known as gaseous, refers to a state of matter. In this state, particles are widely separated and move randomly at high speeds. Gases have no definite shape or volume, expanding to fill any container they occupy. Their properties are described by the ideal gas law, which relates pressure, volume, temperature, and the number of moles of gas.

The transition from liquid to gas is called vaporization or boiling, while the transition from gas to liquid is condensation. Gases can be pure substances, like oxygen or nitrogen, or mixtures, such as air. The behavior of gases can be influenced by external factors like temperature and pressure. For example, increasing temperature generally increases the kinetic energy of gas particles, leading to higher pressure or expansion. Conversely, increasing pressure at a constant temperature compresses the gas, reducing its volume. Understanding the properties of gases is fundamental in various scientific fields, including chemistry, physics, and engineering.
