Discussion Overview

The discussion revolves around the statement "hot objects don't always accelerate," as presented in a video on thermodynamics. Participants explore the implications of this statement and its relation to concepts of work and acceleration.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant expresses confusion about the statement regarding hot objects and seeks clarification on how to understand it.
  • Another participant questions the context of the statement and connects it to the relationship between work, force, and acceleration.
  • A third participant provides an example to illustrate that hot objects do not necessarily accelerate, using the analogy of a stove and a pot of water.
  • One participant acknowledges their earlier question as misguided, suggesting an understanding that heat can flow at a constant rate without causing acceleration.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the interpretation of the original statement. There are multiple viewpoints regarding the relationship between heat, work, and acceleration.

Contextual Notes

Some participants reference the definitions of work and acceleration, indicating a potential misunderstanding of these concepts in relation to the statement about hot objects.

was just watching this video(The joy of science) on thermodynamics, and the proffesor of the video said "hot objects don't always accelerate." this went against what i previously thought. tried googling it but couldn't find an answer. i don't know how to picture this. how?
 
Science news on Phys.org
not sure if i put his statement out of context, but after he mentioned it he went to go on and explain work = acceleration x distance.
 
That is a strange quote, of course hot objects don't always accelerate. If they did then your stove would have to chase your pot in order to boil water. I don't know what they were trying to express.

By the way, work=force.distance not acceleration. If you push a box along the ground you do work, but if the friction force is equal to your pushing force there will be no acceleration despite all the work you do.
 
ok thanks i just realized what a dumb question that was, because the heat can go at a constant flow. thanks
