Question

What is a cryogenic agent?

Answer 1

Introduction of cryogenic agent

• A cryogenic agent is a solid, liquid, or gas that can be used to cool an object to below $–150°\mathrm{C}(–238°\mathrm{F})$ temperatures.
• The creation and behavior of materials at extremely low temperatures are known as cryogenics.
• Oxygen, nitrogen, hydrogen, and helium are the most frequent gases that are converted to a liquid for cryogenics.
• It can be used to produce cryogenic fields for rockets, in MRI machines that use liquid helium and require cryogenic cooling, storing large quantities of food, special effects fog, recycling, freezing blood and tissue samples, and even cooling superconductors.
