Subatomic Phase changes?

    Subatomic Phase changes???

    Hi,

    I was wondering if subatomic particles (electrons of example) experance phase changes. ie A liquid current or gaseous current of electrons.

    Thanks...

    No sugestions?...

    Can a water molecule have a phase change? No.

    Only macroscopic objects can go through phase changes, a couple of molecules of water is not a gas, liquid or solid in any sort of meaningful sense similar to what we think of as gas liquid and solid.

    This is just a metaphorical use of the word current; gases and liquids don't exist on the scale of electrons.

    The theory of phase transitions can certianly be applied to statistical systems of particles (electrons included),but not in the gas,fluid,solid,version.

    in the case of electrons the best known transition would be the transition to Cooperpairs : ie superconductivity...

    In theory, the same happens to mangetic monopoles...beware : this is theoretical physics.

    What about electrons in a DC current. Can you not apply the Ideal Gas laws to them??

    No,electrons are a typical example of Fermi gas...There are books written on Fermi gas.U'll need to understand though that the word "gas" is doesn't have the same significance as the when talking about the gas phase of most substances.

    no the moelecules (when energy givin)

    have more energy so with this energy it has no use for it so it uses it in vabration

    so the moelecules vibrate more and pushes the moelecule further away
    so it become a gas

    thick of it you will get it
