Cryogenic liquids have a boiling point of:

Explanation:
Cryogenic liquids boil at extremely low temperatures, far below freezing. They’re defined by having boiling points well below 0°C, typically around or below -150°C (-238°F). This ultra-cold threshold is why they require specialized equipment and safety measures to store and handle, since even small heat gains can cause rapid boil-off and pressure buildup. If you compare the temperatures given, ordinary water is at 32°F (freezing) or 212°F (boiling), which are nowhere near cryogenic. The negative temperatures shown are cold, but they don’t reach the very low temperatures that define cryogenic liquids. The key idea is that cryogenic fluids boil at temperatures far lower than these values, which is what makes them distinct and demands special precautions.
