What is the term for the process when liquid helium explosively turns into gas?

The process when liquid helium explosively turns into gas is known as a quench. This phenomenon occurs because liquid helium is kept at extremely low temperatures, and when it is exposed to a sudden increase in temperature or pressure, it can rapidly vaporize. The term "quench" is commonly used in cryogenics to describe the act of sudden cooling or the rapid conversion of a cryogenic liquid into gas, which can happen under certain conditions with helium. This change is accompanied by a rapid increase in volume and can lead to an explosive expansion, which is characteristic of the quenching process. The specific behavior of helium during this transition is crucial in various applications, including those related to superconductivity and magnetic resonance imaging (MRI) systems. Understanding this term is essential for those working with cryogenic liquids, as it helps to manage safety and operational procedures when handling such materials.
