Editing Temperature

[[Category: Physics]]
== Explanation ==
Temperature is the way humans measure the average [[thermal energy]] or [[heat]] of a [[thermodynamic system]]. The SI unit of the temperature scale is Kelvin '''K'''. Other temperature scales include the most widely used Celsius '''°C''', and the less used Fahrenheit '''°F''' and Rankine '''R'''. The lowest possible temperature in the universe is known as [[absolute zero]] and is measured in the Kelvin scale as 0 K. At this point, the system would only have the quantum [[zero-point energy]].

== Frequently Asked Questions ==
=== What is the highest possible temperature that can be reached? ===
[[Planck's temperature]] is the highest possible temperature according to the present theories. The temperature can be as high as 1.417×10<sup>32</sup> K. Due to high energy at this temperature, all forces begin to feel the same way, even gravity becomes stronger, thus unifying all four forces.

=== What is the highest temperature ever reached on Earth by humans? ===
It is claimed that the ALICE (A Large Ion Collider Experiment) at the Large Hadron Collider (LHC) had reached about 5.5×10<sup>12</sup> K by colliding [[proton]]s with lead or nuclei to form [[quark-gluon plasma]].<ref>http://blogs.nature.com/news/2012/08/hot-stuff-cern-physicists-create-record-breaking-subatomic-soup.html</ref>
