In summary, the conversation discusses the concept of phase changes in subatomic particles, specifically electrons. It is mentioned that only macroscopic objects can experience phase changes and that the theory of phase transitions can be applied to statistical systems of particles. The transition to Cooperpairs in superconductivity and the theoretical possibility of magnetic monopoles also briefly mentioned. It is clarified that the term "gas" does not have the same meaning when applied to electrons, as they are a Fermi gas. The conversation also briefly touches on the idea of molecules vibrating and pushing each other further apart to become a gas.

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.

A liquid current or gaseous current of electrons.

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
 

1. What is a subatomic phase change?

A subatomic phase change is a transition between different states of matter at the subatomic level. This can occur when the number and arrangement of particles, such as electrons and protons, change.

2. What are the different types of subatomic phase changes?

There are four main types of subatomic phase changes: solid to liquid (melting), liquid to gas (vaporization), solid to gas (sublimation), and gas to solid (deposition). These changes can also occur in reverse, known as freezing, condensation, deposition, and sublimation respectively.

3. How are subatomic phase changes different from macroscopic phase changes?

Subatomic phase changes involve changes at the subatomic level, while macroscopic phase changes involve changes at the macroscopic level. Subatomic phase changes are also governed by quantum mechanics, while macroscopic phase changes are governed by classical physics.

4. What factors affect subatomic phase changes?

The main factors that affect subatomic phase changes include temperature, pressure, and the number and arrangement of particles. These factors can influence the energy and movement of particles, leading to changes in their state of matter.

5. Can subatomic phase changes occur naturally?

Yes, subatomic phase changes can occur naturally. For example, water can evaporate and change from a liquid to a gas due to changes in temperature and pressure. Similarly, rocks can undergo sublimation, or the direct change from a solid to a gas, over long periods of time due to exposure to sunlight and wind.
