To take a substance below 0°C, it typically requires reducing the temperature below the freezing point of water. This can be achieved through cooling methods such as refrigeration, using ice, or employing cryogenic techniques. Additionally, factors like pressure changes and the specific properties of the substance (e.g., its freezing point) can influence how it behaves at low temperatures.
Below permafrost is below freezing temperature (0c)
Where air planes fly, the temperature is below freezing.

Examples: wolfram (3422 0C), rhenium (3186 0C), osmium (3033 0C), tantalum (3017 0C).
Below permafrost is below freezing temperature (0c)
By heating above 100 0C (at standard pressure) or by freezing below 0 0C.
Where air planes fly, the temperature is below freezing.
Salt is effective to temperatures of 20 degrees at which it takes 20 minutes to begin melting the snow. Below 10 degrees its useless by itself. They usually mix it with calcium chloride and this enables to use it to temperatures well below zero. It can be effective at temps of -40 to -50 degrees. The sea water freeze at approx. 28 degrees Fahrenheit (between -2 0C and -3 0C). The freezing point of salted water (with NaCl) depends on the concentration of the sodium chloride. The minimal temperature possible (-21,1 0C) is at a concentration of 23,3 % NaCl.
A liqued turns to ice when it freezes below a temperature of 0C( or 32F )

Melting point: -114 0C Boiling point: 78 0C Density: 0,78945 g/cm3 at 20 0C Refractive index: 1,361 Viscosity: 0,0012 Pa.s For other properties see the link below.
For what? Industrial processes in general operate from way below 0C to thousands of degrees C
Oxygen is liquid at a temperature between -218,79 0C and -182,95 0C.

Blood contains some dissolved salts, which lower the freezing point.
Yes! Clean water can exist in liquid phase even if temperature is under 0 degrees of Celsius temperature scale. This phenomenon is called Liquid hypothermia I think. If clean, distilled water is left to cool down below 0 degrees in a very calm environment, that is if it is not disturbed in any way, and if container in which this water is, is clean, and without a scratch (dust particles can gather on a scratch), than this may happen.
