The zero-curtain effect occurs in cold (particularly periglacial) environments where the phase transition of water to ice is slowed due to latent heat release. The effect is notably found in arctic and alpine permafrost sediments, and occurs where the air temperature falls below 0 ° C (the freezing point of water) followed by a rapid drop in ...
The theoretical temperature is determined by extrapolating the ideal gas law; by international agreement, absolute zero is taken as 0 kelvin (International System of Units), which is −273.15 degrees on the Celsius scale, [1] [2] and equals −459.67 degrees on the Fahrenheit scale (United States customary units or imperial units). [3]
Zero degrees Celsius (°C) coincides with 273 Kelvin. At absolute zero most elements become a solid, but not all behave as predictably as this; for instance, helium becomes a highly unusual liquid . The chemistry between substances, however, does not disappear, even near absolute zero temperatures, since separated molecules/atom can always ...
Working in temperatures of minus 15 degrees (minus 26 degrees Celsius), Villegas said the best way to feel warm was to “just keep moving.” ... chills as low as 30 degrees below zero (minus 34 ...
The temperature in portions of the Yakutia region of eastern Russia, where Yakutsk is located, dropped below 40 degrees below zero Fahrenheit (40 degrees below zero Celsius) during the middle of ...
Extremely cold air sent temperatures well below zero on Wednesday in Siberia, resulting in the coldest weather of the season thus far in a region known for being home to some of the harshest ...
Negative temperatures can only exist in a system where there are a limited number of energy states (see below). As the temperature is increased on such a system, particles move into higher and higher energy states, so that the number of particles in the lower energy states and in the higher energy states approaches equality.

Because liquid droplets commonly exist in clouds at sub-zero temperatures, 0 °C is better defined as the melting point of ice. In this scale, a temperature difference of 1 degree Celsius is the same as a 1 kelvin increment, but the scale is offset by the temperature at which ice melts (273.15 K).
