There is absolute zero to define the coldest. Is there a defining maximum temperture for things on earth.?

Question

I know that all things have a flash point but what is the max temp something can be.

Answer 1

These fusion reaction temps are the highest that I know of:

Physics Laboratory achieved ion temperatures in excess of 58,000,000 oC, the minimum required for a self-sustaining fusion reaction (a condition called ignition), for the first time in 1978. These experiments required a number of advances, most importantly in the development of a powerful new technique for heating a magnetically confined plasma-neutral beam heating. The use of neutral beams to heat plasma dates back to the early 1960s with work performed at the Lawrence Livermore and Oak Ridge national laboratories. Neutral beam heating involves the injection of high currents of energetic neutral atoms into the plasma. The neutral atoms cross the magnetic confinement field and enter the plasma, where they are ionized and confined by the magnetic field. They then heat the plasma through collisions with the plasma ions and electrons. Oak Ridge supplied the neutral beam heating systems used in the Princeton experiments.

Scientific Impact:
Neutral beam heating paved the way for major advances in the next generation of plasma confinement devices, which attained ion temperatures suitable for practical fusion energy production and multi-megawatt fusion power levels. It is believed that practical fusion power production will require plasma temperatures in the range of 100,000,000 oC to 200,000,000 oC.

Answer 2

No maximum temperature. In fact, when you pump a laser, the electron "temperature" effectively goes past infinity into negative territory. In hermodynamics and statistical mechanics, the quantity 1/kT shows up a lot, where

k = Boltzmann Constant = 1.380 65×10^−23 J/K and

T = absolute temperature, in Kelvin

In this expression, the value of T can become infinity, in which case 1/kT becomes zero, a perfectly good value, and negative values also often make mathematical (and physical) sense.

Answer 3

The Planck Temperature is considered to be the maximum meaningful temperature. It's about 1.4 X 10^32 K. Spacetime essentially disintegrates, and the known laws of physics break down at that point.

Answer 4

There is no such maximum that we know of. Think of a car. There is an obvious minimum speed with respect to the ground (zero, stopped), but there is no theoretical maximum. Probably the highest we have achieved is through nuclear fusion (the hydrogen bomb). Even that is not a theoretical limit.

Answer 5

I would guess that the highest temperature thus far attained on Earth is the collision of electron-positron pairs at a trillion electron volts. You might find a temperature equivalent of that at the Cern Labs web site.

Answer 6

Zero is not the absolute zero.

Absolute zero is at: -273º (this is out in space)
lowest man made is:

Maximum: There isn't, but there are limits on how much heat we can produce as humans using the available technology

Answer 7

I guess that depends on how much energy there is in nature and how much you can get together in one space.
No way of measuring that.
Remember that heat is energy and 'cold' is only a concept describing the absence of heat. With absolutely no energy(heat), you can measure this as the lowest temperature.

Answer 8

There is no maximum.
