It is understood that Minimum temperature in any part of Universe is -273 Degree Centigrade = zero degree kelvin. Is it correct? If so how it is calculated? If not what does -273 Degree centigrade indicate?

Theoretically the temperature in any part of the whole universe can not be below -273 degree centigrade (i.e. 0 degrees on the Kelvin scale or about 459.4 degrees on the Fahrenheit scale).
To calculate this temperature, the Kinetic energy of a molecule =3/2kT where k is the constant and T is the absolute temperature in Kelvin. Theoretically the lowest possible kinetic energy is 0 {energy can not be negative}, so in the formula, if Kinetic energy is 0, then T has to be 0 in Kelvin because k is a constant. Therfore the lowest possible temperature of any substance is 0 degrees kelvin.
At 0 degrees Kelvin, all atoms "freeze", seizing all kinetic energy. As the atoms have no kinetic energy at this temperature, the atomic particles will have no motion and electrons will stop revolving around the nucleus and will collapse towards the nucleus. If this happens, things will cease to exist and so will the universe.
Therefore, the minimum temperature of any part of the Universe has to greater than 0 degrees Kelvin or -273 degrees Centigrade

zero kelvin is not the minimum temperature because sub atomic particles still do things at such a temperature. also no mater where you go gravity will tend to heat things up even if just a relatively little bit.
also zero kelvin can be achieved in the hyperluminosphere. and in lab experaments but photographing the results heats up the test and so we can not see things as they might be at zero kelvin.
i am going to get that web site up agean someday where i explain what that is. basicly it is the outermost region of the universe the universe in this case being the place where all the stuff is. the escape velocity of the universe is 2 times the speed of light so anything that goes up at the speed of light comes back down at the speed of light therefore the universe is not expanding or contracting and the big bang could not have happened and if your college taught u that it did u should ask for your tuition money back. i call it the hyperluminosphere because light at that altitude does not shine. light that has gone way up there and come back down to be seen by us has an average temperature of 2 kelvin.
one more thing if a teacher type wants to know just say zero kelvin.

Well, basically, we don't know.
Black holes may have a temperature of absolute zero, since there is likely to not be much molecular activity, but we really don't know.
My guess would be that the minimum temp anywhere in the Universe would always have to be slightly above absolute zero, so -272.00001 degrees Kelvin or something along those lines...

-273 or 0 degrees kelvin indicates that there is no energy in the atoms and/or molecules
p.s. temprature is a measure of energy in th form of heat
0 degrees kelvin is only hypothetical beacuse all atoms are constantly in motion because of their energy and they colide with other atoms to make heat through friction.....and they would have to stop but so far scientists have only gottin to about one bilionth of a degree away from 0 degrees kelvin

For most gases there is a linear relationship between temperature and pressure. Theoretically, at absolute zero the volume of an ideal gas would be zero and all molecular motion would cease.

yes. -273 degrees farenhigt, aka absolute zero is the lowest temperature where there is absolutely no heat. It is very hard to obtain this temperature, and scientists have never come to excactly absolute zero, though they have come close

The minimum temperature is absolute zero. (-273.15*C, 0*K, -459.67*F). Absolute zero is the lowest possible temperature where nothing could be colder and no heat energy (kinetic energy) remains in a substance. Absolute zero is the point at which molecules stop and they have minimal movement vibrations or none, retaining only quantum mechanical, zero-point energy-induced particle motion.

If you can find an area that is completely clean of matter it should indicate zero temperature.

i think on earth is minimum -20
when astronauts dont know abt our universe in detail ( there can be some planets where temperature is -2000 also & even below that )
it could bot be found bcz it is not easy to reach on such planets
