Subatomic mechanism of heat transfer by convection?

Click For Summary

Discussion Overview

The discussion revolves around the mechanisms of energy transfer between gas atoms during convection, focusing on the roles of various subatomic particles such as electrons, photons, neutrons, and protons. Participants explore the nature of collisions and the distinction between convection and conduction in heat transfer.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant questions how energy is transferred between gas atoms of different energies during collisions, seeking clarity on the role of subatomic particles in this process.
  • Another participant asserts that heat transfer via convection primarily involves collisions between electron shells rather than the atomic nucleus, suggesting that the nucleus is mainly involved in translational kinetic energy.
  • A further contribution distinguishes between convection as a mechanism of bulk mass transport and conduction as the actual method of heat transport through momentum and energy exchange between atoms.
  • It is noted that in a plasma state, nuclei can participate in collisions, alongside free electrons, but this requires relatively high temperatures.

Areas of Agreement / Disagreement

Participants express varying views on the specifics of energy transfer mechanisms, with some focusing on the role of electrons and others discussing the involvement of nuclei in certain conditions. The discussion does not reach a consensus on the precise mechanisms at play.

Contextual Notes

There are limitations regarding the assumptions made about the roles of different particles in heat transfer, particularly in distinguishing between conduction and convection, as well as the conditions under which nuclei may participate in collisions.

Hey. I've been pondering on and off for a while now how exactly energy is transferred between two gas atoms, with different energies, via collision. Specifically how the electrons, photons, neutrons, protons, and any other particles that are used for energy transfer in convection, interact. If you need me to restate the question or clarify any point of it, just ask.

...I've managed to ask my question without a question mark...yay? Whoops.

So what's the question?

Heat convects via collisions. You know that. Doubtful that the nucleus is involved except in translational kinetic energy. Mostly the collision is bouncing electron shell off one another. Any help?
 
First of all, convection (either force or natural), is a mechanism of bulk mass transport. In the case of natural convection, it means there is some cooler (denser) mass (of gas) moving down the gravity field while the warmer (less dense) mass rises.

Conduction is the actual heat transport method which works by momentum/energy exchange between atoms.

The protons and neutrons are fixed in the nuclear surrounded by the electrons, and atomic collisions (not nuclear) occur between the electrons surrounding the atoms.

Photons interact primarily with the electrons, but have very little momentum.

Now in a plasma, one can have nuclei participating in collisions with other nuclei, as well as free electrons (there are ion-ion, ion-electron and electron-electron collisions) - but the temperature has to be relatively high.
 
Excellent, thank you.
