what is the hottest possible temperature?

Answer 1

the sun

Answer 2

The absolute possible hottest temperature is the Planck temperature, on the order of 10^32 Kelvin. It's not clear that "hot" has any meaning past that scale.

The hottest temperature ever achieved on earth is 10^12 Kelvin (in a very small space, for a very short time) at the Relativistic Heavy Ion Collider at Brookhaven National Laboratory in New York.

Answer 3

The Planck temperature, named after German physicist Max Planck, is the unit of temperature, denoted by TP, in the system of natural units known as Planck units. It is one of the Planck units that represent a fundamental limit of quantum mechanics. The Planck temperature is the fundamental upper limit of temperature; modern science considers it nonsensical to conjecture about anything hotter. It is the temperature of the Universe during the first instant (the first unit of Planck time) of the Big Bang according to current cosmology.

1.41679(11) × 1032 K

where:

mP is the Planck mass

c is the speed of light in a vacuum

is the reduced Planck constant (or Dirac's constant)

k is the Boltzmann constant

G is the gravitational constant

The two digits between the parentheses denote the uncertainty (standard deviation) in the last two digits of the value.

Answer 4

Yea verily, what Crabboy sayeth is true.

Before Plank time, temperature has no meaning in our universe. At Plank time, when the Plank temp. was existant, the universe was at the highest termperature it could support and still be a part of our universe. Since Plank time, the universe has been cooling off. In the end, a few years from now, the universe will probably snuff out like a candle when it reaches absolute zero (K = 0).

Answer 5

I would imagine the temperature close to a black hole would be close to the hottest found today.

The temperature of the core of the sun is approx 14 million Kelvin, where as the temperature of matter being dragged in to a black hole can reach 100's of millions degrees.

Answer 6

1.4 × 10^32 K: Planck temperature. This is the temperature 5×10^(-44) seconds after the Big Bang.

Answer 7

The simple answer is that there is not one. Temperature as you know it is the average kinetic energy. That is basically

(sum(.5*mi*vi^2) for i=1:amount of particles) /amount of particles

now technically there is an absolute temperature. if you have every mass in the universe traveling at the speed of light that would be

sum(.5*mi*(3.0E8)^2 for i = 1:amount of everything in the universe)/ amount of everything in the universe


but that would be impossible to measure


oh yeah, planks temperature, that's what I described.

Answer 8

Theoratically there must b a highest possible temparature b'cauz as temp increases the electrons move to more farther orbits..and possibly to infinity...As temp even more increases there shall b a disintegration of the nucleus...(the plasma stage) and finally they gain a kinetic energy equal to the velocity of light...after v cant imagine wat would happen for light is the fastest known substance.
and v shall never b able to measure this temparature.....Till date the hottest poposed temparature is at the time of big bang

Answer 9

How would we know? We would die at anything above 100 degrees celcius, at the most, so we're not exactly going to be able to put a thermometer there and then come back and check it are we?

Answer 10

I don't think there is one. The molecules just keep moving faster and faster. There's a lowest possible temp, though, called absolute zero, and that's where 0 Kelvin is defined.

Answer 11

on the surface of the earth (volcanos r very very hot)
if u get into the earth below the surface (the core is extremely hot)

in the universe, the stars r too hot (our sun is a middle size & temprature star), there is stars much greater & hotter than our sun
