Cryonics uses temperatures below −130 °C, called cryopreservation, in an attempt to preserve enough brain information to permit the future revival of the cryopreserved person. Cryopreservation may be accomplished by freezing, freezing with cryoprotectant to reduce ice damage, or by vitrification to avoid ice damage.What is it called when something is frozen?
verb. if a liquid freezes or something freezes it, it becomes solid because it has reached a low temperature.Is 0 degrees a frost?

When the temperature is negative, i.e. below 0 °C, then we know that it is so cold that water will freeze. Water will always be ice below 0 °C, liquid from 1 to 99 °C, and steam from 100 °C upwards.Which is colder 0 C or 0 F?
freezing levelsBelow the line, the air is warmer than 0°C. The freezing level is the height where the air is 0 degrees Celsius (0 °C) or 32 degrees Fahrenheit (32 °F). Higher than the freezing level, the air is colder.
Can it snow at 25 degrees?
Snow forms when the atmospheric temperature is at or below freezing (0 degrees Celsius or 32 degrees Fahrenheit) and there is a minimum amount of moisture in the air. If the ground temperature is at or below freezing, the snow will reach the ground.Is water colder than 32?
And water freezes at 32 degrees Fahrenheit. But it can actually get colder than that, all the way toward what we call absolute zero. This value is equivalent to about -459 degrees Fahrenheit. This is when the water molecules are basically not moving.Can it snow at 37 degrees?
It turns out that you don't need temperatures below freezing for snow to fall. In fact, snow can fall at temperatures as high as 50 degrees.

Cryogenic freezing as applied to food, can be defined as very rapid freezing achieved by exposing food to a very cold refrigerant that usually undergoes a change of state while the food is being frozen.What is sub temp?
A body temperature below the normal range of 97.5° to 99.5°F (36° to 38°C).Can you freeze air?
Yes, you can freeze air, and yes, each ingredient of air will freeze at a different temperature, so that if you were to take a jar of air and slowly make it colder and colder, each different ingredient would freeze into a different layer, just as you suggest.Which one freezes in winter?
