Gas of elementary particles

SandeshPhy

can a gas of neutrons said to behave like ideal gas?
neutrons almost satisfy all postulates of kinetic theory.(except maybe about newtons laws)

Also can a gas of protons said to be a ideal gas?
protons could be said to be simply hydrogen with electrons removed.
the electrons don't have major role in dynamics of atoms.

I would say neutrons could fit all the assumption in the kinetic theory of gases therefore a good candidate.
Protons are +charged and therefore, I would say, do not satisfy the assumption that there is no force between particles used in the development of the kinetic theory........unless there is a very low concentration of protons ???

SandeshPhy

But for neutrons can we say newton's laws will be fully applicable??

For neutrons you can have an ideal gas, as long as the density is low enough, but for protons, no, because they are charged particles. For forces that fall off quickly enough, you can have an ideal gas if the density is low enough, but the electromagnetic force does not fall off quickly enough.

Electrons in a metal are siad to behave like an ideal gas and is the basis for theory of conduction.

Yes. The metal atoms are positively charged, so the electrons don't feel repulsion from each other over long distances, because the metal ions counteract the negative charge of the electrons.
