Külmgaasi

Külmgaasi refers to a substance that is in a gaseous state at temperatures significantly below room temperature. This often implies that the gas is a vapor at standard atmospheric pressure, but can be liquefied or solidified at lower temperatures or higher pressures. Common examples of substances that might be referred to as külmgaasi include refrigerants used in cooling systems like R-134a or ammonia, as well as atmospheric gases such as oxygen, nitrogen, and argon when they are stored or transported in their liquefied forms. The term highlights the low temperature required to maintain the gaseous phase under certain conditions. Handling külmgaasi requires specialized equipment and safety precautions due to their low temperatures and potential for rapid expansion if released. Applications range widely, from industrial processes and medical uses to scientific research and consumer products. The specific temperature at which a gas is considered "külm" can be relative to its critical temperature and ambient conditions.
