Is achieving absolute zero (Zero Kelvin) or below, possible?

Question

I know that at absolute zero, all particles stop, so wouldn't lower be impossible?

Answer 1

No, if you were to graph out the relationship between volume and temperature, as the temperature decreases, so does the volume. So if something was at 0 kelvin, the volume would be zero, and because of the law of conservation of matter, you have something with volume and cause it to go down to zero volume.



It can also be proven with the equation PV=nRT...if T=0, that would mean that there is either zero pressure or zero volume, which is impossible

Answer 2

Achieving Absolute Zero

Answer 3

One of the basic laws of thermodynamics is that achieving absolute zero can't be done. In this case, Zeno's rabbit never catches the tortoise.

Answer 4

At zero Kelvin the neutrinos collapse in on themselves and create a black hole.

Might be wrong about which particle collapses but I'm sure they would create a black hole.

Don't try at home.

Answer 5

No. It is a CALCULUS LIMIT...not a physically possible condition.



The closest we've ever achieved is 100 picokelvin.
