Absolute Zero (0K)(-273....C) is the Temp at which all elements, compunds etc. are in a solid state, so then why are nebulae and other things in space refered to as gas clouds????

i realise that space is not 0k, and it is unatainable, but you get my point

"Outer" space, itself, has a background temperature of several (degrees) K, so even space is not at absolute zero.
Those nebulas are not that cold, either. They are actually pretty hot. They are radiating in the infared, visible, and even up to X-ray energies, which can be up to several 1000 K. They would definitely be a gas at several 1000 K.

Absolute zero is unattainable.
In order to transfer the heat necessary to lower the temperature from 1K to 0K there must be a heat sink lower than 0K for it to go. Since, by definition absolute zero is as low as you can go, it ain't possible.
Also, absolute zero has nothing to do with the state of matter. 0 degrees K simply means that all of the atoms at that temperature cease all motion.

Because nothing exists at absolute zero. The nebulae ar not at absolute zero.

First, stuff out in space is not 0ºK. Second, even if you could get 0ºK you would have zero point fluctuations the way for Nature to tell you that Heisenberg uncertainty still works at minimum energy.

it is true that these objects are not really clouds. i believe that this kind of inaccuracy is overlooked for the convenience of conversation. a more accurate way of referring to the nebulae might be just calling them molecules suspended in space (a vacuum).

They end shifting; interatomic forces grow to be somewhat more beneficial major than the forces of kinetic interaction and the gasoline finally freezes right into a strong, in additional than a number of circumstances in the crystal type dictated through the gasoline molecules electron configuration.

They are not at absolute zero. There's a time element and entropy involved.
