Discussion Overview

The discussion centers around the question of why systems tend to prefer the lowest energy state, exploring the underlying physical laws and concepts of equilibrium. Participants examine the implications of energy states in various contexts, including forces and fields.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants suggest that the tendency of systems to prefer lower energy states is a direct result of physical laws, though they acknowledge difficulty in providing a clear explanation.
  • There is uncertainty about the terminology, with some arguing that "prefer" may not be the correct word, instead suggesting that systems tend toward equilibrium due to imbalances.
  • One participant mentions that the physical laws involved depend on the specific system in question, indicating variability in the explanation.
  • Another participant introduces the idea of an imbalance of forces as a potential explanation for why systems move toward lower energy states.
  • It is noted that energy can dissipate from a system and that achieving a higher energy state requires energy input, leading to a statistical tendency for systems to lower energy states as energy spreads out.
  • Examples involving electric and magnetic dipoles are raised to illustrate the alignment of these dipoles in external fields, suggesting that forces act on them to cause this alignment.

Areas of Agreement / Disagreement

Participants express differing views on the terminology and the nature of the processes involved, indicating that multiple competing perspectives remain without a clear consensus on the explanation for systems preferring lower energy states.

Contextual Notes

Participants highlight the dependence of explanations on the specific system being discussed, and there are unresolved questions regarding the nature of the imbalances and forces involved.

Hello friends... Please answer to this question…
Any system always prefers a lowest energy state. Why? Does this fact come from any physical laws?
 
Science news on Phys.org
That's a pretty interesting question. I would say it is a direct result of physical laws, but I really couldn't give you a good explanation.

Also, please don't make your text way bigger than it needs to be. It's like talking really loudly into someones ear.
 
I am not sure prefer is the right word, but a system would tend toward equilibrium due to an imbalance of some kind. From a less to more stable state. The physical law involved will depend on the system in question.
 
Sorry about the font. i didn't meant to talk loud. Please forgive...

imbalance of what?
 
An imbalance of forces perhaps.

If you ask a more specific question, I can try to give more specific answers.

Energy can dissipate from a system and be converted to other forms but to get the system to a higher energy state requires you put energy into it. When the energy is dissipated, some sorrounding system will absorb the energy and enter a higher energy state. Energy is conserved. But overall, there will be a statistical tendency for systems toward lower energy states as the energy "spreads out" more.
 
Say for example this:
why does a (electric/magnetic)dipole placed in external electric/magnetic field align itself parallel to the field. Why?

Because it feels a force that causes it to do so.
