Absolute zero is the lowest limit of the thermodynamic temperature scale; a state at which the enthalpy and entropy of a cooled ideal gas reach their minimum value. The fundamental particles of nature have minimum vibrational motion, retaining only quantum mechanical, zero-point energy -induced particle motion.
The next world record low temperature was a reading of −88.3 °C (−126.9 °F; 184.8 K), measured at the Soviet Vostok Station in 1968, on the Antarctic Plateau. Vostok again broke its own record with a reading of −89.2 °C (−128.6 °F; 184.0 K) on 21 July 1983. [8] This remains the record for a directly recorded temperature.
The theoretical maximum possible ground surface temperature has been estimated to be between 90 and 100 °C (194 and 212 °F) for dry, darkish soils of low thermal ...
Performing this transformation adiabatically while keeping the atoms in the Mott insulator regime, it is possible to go from a low entropy positive temperature state to a low entropy negative temperature state. In the negative temperature state, the atoms macroscopically occupy the maximum momentum state of the lattice.
Aware that most Americans have at least two given names, he invented two more given names based on the scientific name for a house cat, Felis domesticus, and abbreviated them accordingly as F. D. C. His article, entitled "Two-, Three-, and Four-Atom Exchange Effects in bcc ³He" and written by J. H. Hetherington and F. D. C. Willard, was ...
Experimentally, absolute zero can be approached only very closely; it can never be reached (the lowest temperature attained by experiment is 38 pK or 38 trillionths of a Kelvin). [4] Theoretically, in a body at a temperature of absolute zero, all classical motion of its particles has ceased and they are at complete rest in this classical sense.

Nuclear fusion is normally understood to occur at temperatures in the tens of millions of degrees. This is called "thermonuclear fusion".Since the 1920s, there has been speculation that nuclear fusion might be possible at much lower temperatures by catalytically fusing hydrogen absorbed in a metal catalyst.
