What is the highest temperature possible

Question

the lowest is absolute zero at -273 degrees. am i right?

Answer 1

The highest temperature indirectly observed within our solar system is at the core of our sun, with a value of about 2 x 10^7 K. Our sun has a surface temperature of 5.73 x 10^3 K.Very massive stars (M > 10 solar masses) appear bluish in optical telescopes and have surface temperatures of about 2.5 x 10^4 k but have core temperatures in the region of 10^8 K. Type II supernovae (stars that have ended their fusion core life and still have masses greater than about 2 solar masses) explode with a luminosity of 10^42 to 10^46 W and achieve temperatures sufficient to create all of the known elements via the process of nuclear fusion. The peak explosive temperature of these detonating stars may well be in excess of 10^9 K! During the early stages of the initial 'Big Bang', that created our universe, there well may have been temperatures much greater than 10^9 K!

Answer 2

actually you can have temperatures hotter than infinite and those are negative temperatures.

To quote from some web site "So negative temperatures are on the other side of infinity from positive numbers.

Negative temperatures are hotter than infinity."

I've included a few references. Probably the last is the easiest as it is also the shortest. It would have been nice if they had written more.

Answer 3

There is no agreed-upon value, among physicists, for a maximum possible temperature. Under our current best-guess of a complete theory of physics, the maximum possible temperature is the Planck temperature, or 1.41679 x 10^32 Kelvins. This translates to about a quarter of a hundred nonillion degrees Fahrenheit (2.5 x 10^32). However, it is common knowledge that our current theories of physics are incomplete, thus leaving open the possibility of still higher temperatures.

Answer 4

The coldest possible temperature is +0 Kelvins. The hottest possible temperature is -0 Kelvins. Negative temperatures are all hotter than positive temperatures, and -0 is the hottest temperature there is: the temperature at which it is so hot that all particles are in the uppermost quantum state and no random motion remains.

Answer 5

There is no maximum. It's like saying what's the most mass possible. -Tempurature is the average kinetic energy of particles. At -273 celsius (0 degrees kalvin), there is no kinetic energy, all particles are still (which is impossible, 0K can never actually be reached). There is no limit to how much movement particles can have. The early universe was unbelievably hot, but theoretically, it could still have been hotter.

Answer 6

i dont know about the highest

but yes the lowest is -273.15 Celsius (0 Kelvin)

and no it is not possible to go below, as at the absolute zero the atoms (particles) stop moving

this temp has never quite been achieved, but we have gotten within 0.0001 of absolute zero ))

Answer 7

it depends if singularities exist or if they are just very small spheres. if singularities exist the maximum temperature should be infinite, since temperature is the amount of heat in a certain area. if that area is 0, and there is heat there, it would have infinite temperature.
