Homework Help Overview

The discussion revolves around the comparison of temperature (T), energy (E), and volume (V) in the context of an explosion occurring within a box. Participants are exploring the implications of energy conservation and the changes in energy forms during the explosion.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • Participants are questioning the logic behind the original poster's selections of answers, particularly regarding the implications of energy conservation and the conditions of the box. There is also discussion about the relationship between volume, temperature, and energy during the explosion.

Discussion Status

The discussion is ongoing, with participants providing insights and questioning each other's reasoning. Some guidance has been offered regarding the assumptions made about energy changes and the conditions of the box, but no consensus has been reached.

Contextual Notes

Participants note the specific condition that the box will contain the explosion without deformation, which raises questions about the energy dynamics within the box. There is also mention of the time frame of 0.1 seconds during which energy conservation is considered.

The Attempt at a Solution


I currently think that a and e are correct. But I am not sure what happens to the energy IN THE BOX. When the box explodes, the energy of the contents changes from potential to thermal, sound and kinetic energy. Thus by conservation of energy there is no change in energy of the contents...

Am I right?

Thanks!

There's probably some debate room on a few of these. But why did you check a) if they specifically said in a box that will contain the explosion without deformation? And if you say there is no change in the energy inside the box, why didn't you check c)? Not sure I get the logic here. Surely ONE of b,c or d must be true? I mean they contain all possibilities.

OH, I totally did not see that. Alright so the volume remains constant, and the temperature increases drastically. In those 0.1s, the energy is conserved so I will pick c and e.

That's plausible and probably approximately correct. But if you've got sound energy generated inside the box it could probably get out in less that 0.1 sec, yes? This the 'debatable' thing.
