Cryogenic engineering

Cryogenic engineering is a specialized field of engineering that deals with the production and application of very low temperatures, typically below -150 degrees Celsius (approximately -238 degrees Fahrenheit or 123 Kelvin). At these temperatures, the properties of materials can change significantly, and many gases become liquids, which can be exploited for various industrial and technological processes. Key aspects of cryogenic engineering include: 1. **Cryogenic Liquefaction**: Processes to convert gases like nitrogen, helium, and hydrogen into liquids.
