What's the energy source for the Van der Waals' forces?

Click For Summary

Discussion Overview

The discussion revolves around the energy source for Van der Waals forces, specifically exploring the interactions between dipoles and neutral molecules. Participants inquire about the nature of this energy and its origins, including potential connections to fundamental concepts like the Big Bang.

Discussion Character

  • Exploratory
  • Debate/contested

Main Points Raised

  • One participant questions the source of energy for the attraction between dipoles and neutral molecules, suggesting it might be related to the permanent charge of particles or even the energy of the Big Bang.
  • Another participant asserts that the electrostatic field from charges serves as the source of energy, emphasizing that dipoles and charges interact as a fundamental aspect of their behavior.
  • A follow-up inquiry seeks clarification on whether the energy source could be attributed to the Big Bang, linking elementary particles' permanent charge to this origin.
  • Further discussion raises the idea of a system where forces are consistently present, questioning whether the energy source could be finite or if it persists indefinitely.
  • A brief statement asserts that energy is conserved, though the implications of this in the context of the discussion remain unclear.

Areas of Agreement / Disagreement

Participants express differing views on the nature of the energy source for Van der Waals forces, with some proposing electrostatic interactions while others explore the connection to the Big Bang. The discussion does not reach a consensus.

Contextual Notes

The discussion includes assumptions about the nature of energy and its conservation, as well as the implications of linking fundamental forces to cosmological events like the Big Bang. These aspects remain unresolved.

Hi, I know that if you put a dipole and a neutral molecule at a certain distance, there is the Debye's force that attract them. If you put the same molecules in the first position, they will attract another time.

I know this can be a stupid answers, but what's the font of that energy? The permanent charge of the paricles? If yes, is it the energy of the Big Bang?

Hi,

With font you mean source, right ?
And I would say the electrostatic field from the charges is the source. Dipoles interact. Charges interact. It's what they do for a living.

Searching for anything deeper gets you into endless threads with less relevant content :rolleyes: (there will be folks with a different opinion, though).

Thank you very much! Yes I mean source, sorry for my bad english :D. Anyway, is that source the Big Bang energy? The charges are the elementary particles, with a permanent charge, so that charge is alimented by the Big Bang energy, is it correct?

If you put the system in the starting situation every time the forces are present and re-attracts/repells the moleculs in the same way, creating a loop, isn'it right? But the source of energy should finish, or no?
 
Energy is conserved
