What is the lowest body temperature ever?

Answer 1

May '08, the lowest temperature ever reached is 10^-10 K.

See related link for more information about the Nova Program.

At the Low Temperature Lab at the Helsinki University of Technology on August 12, 2000, they cooled a piece of rhodium metal to 100 pK, or 100,000 nK, or 100 trillionths of a degree above absolute 0.

The lowest temperature a gas of *fermions* has been cooled to is 50 nK (50,000 pK), creating the first fermionic condensate, which is another state of matter like Bose-Einstein condensate, solid, liquid, and gas. This was accomplished with sodium-40, an isotope with half-integer spin, thus making it *fermionic*, so it obeys the Pauli-Exclusion Principle, which is why it's such a feat to get the atoms cold enough for their de Broglie wavelengths to be comparable to their average separation distances from each other. You'll note the temperature is relatively high compared to the above temperatures - the reason is that the repulsive force from the atoms not wanting to be in the same ground energy level makes it more difficult for scientists to cool them.

The lowest temperature a macroscopic (relatively large) object has been cooled to is 0.8 K on April 8 2007 at MIT. The object was a massive whole gram, versus above, where we're talking about hundreds or thousands of mere atoms.

Answer 2

2 billion Kelvin (2 million degrees Celsius, created in the `Z machine`, located at Sandia's main site in Albuquerque, New Mexico.

Proton collisions at CERN have indicated that temperatures of around 10 trillion °C have been achieved within the Large Hadron Collider.)

Answer 3

The lowest body temperature ever recorded in a human with accidental hypothermia who survived was 56.7°F (13.7°C). This person fell into icy water and was successfully resuscitated.

Answer 4

The lowest temperature ever recorded was in Antarctica at -89.2˚C (-128.6˚ F). 

Answer 5

The lowest natural temperature ever recorded at the surface of the Earth was −89.2 °C (−128.6 °F; 184.0 K) at the Soviet Vostok Station in Antarctica, on July 21, 1983.

Answer 6

2 Billion K or 3.6 Billion Fahrenheit

Answer 7

Lowest temperature ever reached in a lab is 100 picokelvin = 0.0000000001 K (1*10^-10 Kelvin) in a laboratory from Helsinki University, in 2000.

Answer 8

The record-low temperature was reached in a piece of rhodium metal, which was cooled to 100 pK. This is one-degree above absolute zero, a temperature that can never be reached.

Answer 9

The coldest possible temperature is absolute zero - defined as 0o kelvin. In 2000 in Helsinki, a temperature of 100 pK (1×10−10K) was achieved.

Answer 10

One of the lowest documented body temperature from which anyone has recovered was 13.0 °C (55.4 °F) in a near-drowning incident involving a 7-year-old girl in Sweden in December 2010.
