Is it possible for heat to be a physical form?

Click For Summary

Discussion Overview

The discussion revolves around the concept of heat as a physical form, specifically whether heat can be stored or contained in a tangible way, akin to a physical object. Participants explore theoretical implications and analogies related to the nature of heat.

Discussion Character

  • Conceptual clarification, Debate/contested

Main Points Raised

  • Some participants question the feasibility of having a "jar of heat," suggesting that heat is not a physical entity that can be contained like solid objects.
  • One participant draws a comparison to other abstract concepts that cannot be physically contained, such as speed or logic.
  • Another participant references the phlogiston theory and discusses the nature of heat in relation to phonons, indicating a distinction between heat as a concept and its representation in physical terms.
  • A humorous remark is made about using a "bucket of BTUs" to illustrate the idea of heat, while also cautioning about the dangers of touching it, implying a playful acknowledgment of heat's physical effects.

Areas of Agreement / Disagreement

Participants generally disagree on the possibility of heat being a physical form that can be contained, with various viewpoints presented without a consensus.

Contextual Notes

Some claims rely on interpretations of physical concepts and definitions of what constitutes a "physical form," which may vary among participants.

By physical form I mean stored chemical or actual be a physical thing you can touch. Yes I understand it already is a physical form in atoms but I mean is it possible to have a jar of heat.

You mean like Sterno?
 
No, you can't have a jar of heat. You also can't have a jar of blue (although you can have a jar of blue paint), you can't have a jar of speed, you can't have a jar of acceleration and you can't have a jar of logic. Plenty of things that can't be jarred.

The phlogiston theory has been falsified by the experimental observation that heat can be produced in any amount without consuming any other substances. One might consider phonons to be heat-particles but I wouldn't call that a chemical.

Well, I always use a bucket of BTUs to warm up on those cold mornings. :rolleyes:

But be careful touching the bucket - you can burn yourself. It is full of heat after all. :wink:
