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 ...
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]
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.

Temperatures could drop as low as 20 to 30 degrees below zero in the northern Plains both Friday and Saturday night and combine with gusty winds to make for frigid wind chills as low as 50 degrees ...
The temperature announced reflects that of the ice surface, while the Vostok readings measured the air above the ice, and so the two are not directly comparable. More recent work [5] shows many locations in the high Antarctic where surface temperatures drop to approximately −98 °C (−144 °F; 175 K). Due to the very strong temperature ...
On the empirical temperature scales that are not referenced to absolute zero, a negative temperature is one below the zero point of the scale used. For example, dry ice has a sublimation temperature of −78.5 °C which is equivalent to −109.3 °F. [97] On the absolute Kelvin scale this temperature is 194.6 K.
The high temperature in Washington, DC, on Wednesday could top out in the mid-50s — 10 to 15 degrees lower than normal for mid-October. Atlanta could struggle to break into the low 60s on ...
Arctic weather enfolded swathes of Russia on Tuesday, with temperatures in the wilds of Siberia falling to minus 58 degrees Celsius (minus 72 degrees Fahrenheit). Yakutsk, one of the world's ...
