1. What are cryogenic gases, and how cold do they have to be?
2. How do cryogenic vessels work, and what is the temperature of the cryogenic gas when it reaches the pressure gauge?
1. Cryogenic gas, or cryo gas, is a medium that was gaseous at ambient temperatures and atmospheric pressures, but has since become a liquid due to cooling and compression. At ambient temperatures and atmospheric pressures, gases occupy a huge volu ...
