## System in lowest energy sate

Hello friends... Please answer to this question…
Any system always prefers a lowest energy state. Why??? Does this fact come from any physical laws?
 Recognitions: Gold Member 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.
