What Happens to Atoms and Energy at Absolute Zero?

Click For Summary

Discussion Overview

The discussion revolves around the concept of absolute zero, exploring its implications on atoms and energy. Participants are curious about the behavior of atoms at this temperature, the nature of energy within atoms, and the potential changes in matter properties as temperatures approach absolute zero.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions what happens to atoms at absolute zero, specifically regarding the energy that keeps atoms together and whether losing that energy would alter their properties.
  • Another participant explains that atoms are held together by electrical attraction between electrons and the nucleus, suggesting that low temperatures do not affect these bonds directly.
  • A different viewpoint states that absolute zero cannot be physically attained, implying that it is more of a theoretical limit rather than a reachable state.
  • Another participant introduces the concept of Bose–Einstein condensates, noting that at very low temperatures, bosonic atoms can condense into a new state of matter, which includes unique properties like superfluidity and quantized vortices.

Areas of Agreement / Disagreement

Participants express differing views on the attainability of absolute zero and the effects on atomic structure and properties, indicating that multiple competing perspectives remain unresolved.

Contextual Notes

There are limitations in the discussion regarding the assumptions about atomic behavior at low temperatures and the definitions of states of matter, which are not fully explored.

i am in the 9nth grade and i am intrigued by the idea of Absolute zero and the phenomenas, my question is what will happen if we reach absolute zero? i know that molecules slow down until they stop, but i don't understand one thing, what is keeping the atoms together, isn't it energy. is there energy within the atom? , what will happen if it losses that energy wouldn't it loss its properties? and if it does, what will it be called by then, because it wouldn't be an atom no more?.
 
Science news on Phys.org
Atoms are held together in molecules by the electrical attraction between the negative electrons and the positive nucleus.
This isn't affected by low temperatures, at high temperatures molecules can break apart into individual atoms because their motion is enough to break these bonds.

Absolute zero only really describes the motion of atoms and molecules in a gas - and even then this is an simple picture
 
I'd start by reading here for a basic understanding: http://en.wikipedia.org/wiki/Absolute_zero

As far as I'm aware, absolute zero doesn't exist as a possible temperature to attain - you physically can't reach it.
 
As you approach absolute zero, there are changes in the properties of matter. Its called a Bose–Einstein condensate. Einstein demonstrated that cooling bosonic atoms to a very low temperature would cause them to fall (or "condense") into the lowest accessible quantum state, resulting in a new form of matter. This includes forms like superfluids and phenomenon including quantized vortices.
