Can Protons and Neutrons Behave Like an Ideal Gas?

Click For Summary

Discussion Overview

The discussion centers around the behavior of protons and neutrons in the context of kinetic theory and whether they can be considered as ideal gases. Participants explore the conditions under which neutrons might behave like an ideal gas and the implications of the charged nature of protons on this classification.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants propose that neutrons could behave like an ideal gas, as they satisfy most postulates of kinetic theory, with some questioning the applicability of Newton's laws.
  • Others argue that protons, being positively charged, do not meet the assumption of no inter-particle forces necessary for ideal gas behavior, unless present at very low concentrations.
  • A participant suggests that while neutrons can be considered an ideal gas under low density conditions, protons cannot due to the nature of electromagnetic forces, which do not diminish quickly enough.
  • Another point raised is that electrons in metals can behave like an ideal gas, as the positive metal ions mitigate the repulsion between electrons over long distances.

Areas of Agreement / Disagreement

Participants generally agree that neutrons may behave like an ideal gas under certain conditions, but there is disagreement regarding protons, with multiple competing views on their classification as an ideal gas due to their charged nature.

Contextual Notes

There are limitations regarding the assumptions made about the applicability of Newton's laws to neutrons and the conditions under which protons might be considered in the context of kinetic theory.

Who May Find This Useful

This discussion may be of interest to those studying kinetic theory, particle physics, or the behavior of gases in different contexts, particularly in relation to charged particles and their interactions.

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 ?

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.
