What is the hottest temperature theoretically attainable?

It is interesting that infinite temperatures are not ruled out by the theory of thermodynamics, but it is also interesting that it is not possible to heat a body to an infinite temperature. In order to heat a body you need a hotter body - which is not possible when you reach infinite temperatures.\nSome really hot things that I can think of are: \nThe centre of the Sun: 15,600,000 K \nThe corona (outer atmosphere) of the Sun: over 1,000,000 K \nThe tenuous electron gas in clusters of galaxies: 100,000,000 K \nAccretion disks around stellar mass black holes: over 1,000,000 K

Hot enough to fry eggs.\nIt won't ever snow there.

True... the Dallol Depression in Ethiopia and Death Valley in California are the two hottest places on earth...\n\nBut the highest ever documented? El Azizia in Libya recorded a temperature of 136 degrees Fahrenheit (57.8 Celsius) on Sept. 13, 1922 -- the hottest ever measured and in Death Valley, it got up to 134 Fahrenheit on July 10, 1913.

Water has the highest specific heat of any of the above-mentioned materials.

Sin's answer makes sense, but in terms of the environment I'd have thought it would be the highest temperature which combined with wind chill would take the felt temperature down to 0C/32F. But don't trust me - I'm not a scientist.

Are you serious? Every possible temperature is in both Fahrenheit and Celsius whether it's hot or cold. Depends where you live if you use F or C.

Could be. There is so far no way to know the temperature of the earth's core. We know from drilling that the temperature increases about 1 degree Fahrenheit for every 60 feet in depth. Of course, there is considerable variation in this from region to region, since it depends on the thickness of the crust, volcanic activity, ocean depth, etc. Anyway if you extrapolate that towards the core, it would give you an answer much greater than 12,000 degrees F. Most sources estimate about 7500 Kelvin or 13,040 F. We can attempt to model the core to calculate the temperature but since we don't know for sure what it is made of, and cannot reproduce the extreme pressure, it is hard to really know the temperature.

Well, if you're talking about water, that would be 0 degrees (freezing) and 100 degrees (boiling)

The hottest superconductors known to man are the cores of neutron stars.  Estimated temperature 10^9 degrees Kelvin.  Source: www.astro.umd.edu/~miller/nstar.html

Depends on what you are burning.  I know you can get paper to 451 farenheit, because it will burn.  (You do know about Ray Bradbury's book, don't you?)  It would be interesting to know whether there are any limits, given that solar energy is really nuclear power.  Any science majors want to tackle the experiment?  Burn different materials with known flash points?

Highest temp ever recorded was 136 deg. F at El Azizia (Libya) in 1922. This is not officially recognized by all.\n\nDeath Valley, CA, USA has the hottest temperature in the world at 134 deg. F.

false - temperature is a measure of heat

close to absolute zero or -273.15 deg C\nst\nIn 1994 the NIST achieved a record cold temperature of 700 nK (billionths of a kelvin).  In 2003, researchers at MIT established a new record of 0.5 nK.

There is a formula...but this is much easier\n\nhttp://www.onlineconversion.com/temperature.htm

The coldest temperature that anything can reach is –273.15 °C. That is called "absolute zero". On the Kelvin scale, which uses the same divisions as the Celsius scale, it is zero, making the point at which water freezes 273.15 °K. Absolute zero is the point at which all atomic movement ceases, i.e. the atoms no longer move relative to one another.\n\nAny material can be heated or cooled to any temperature, as long as enough energy can be added or removed to do so. Materials left in an environment for long enough will reach the same temperature as their surroundings. This is known as reaching equilibrium with the environment.
