Comparison of T, E and V in different states?

Homework Statement

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.

I would say that the comparison of temperature (T), energy (E), and volume (V) in different states is an important aspect of understanding the behavior of matter. When the box explodes, the energy of the contents does indeed change from potential to thermal, sound, and kinetic energy. This is due to the conversion of potential energy into other forms of energy, as predicted by the law of conservation of energy. However, it is also important to consider the changes in temperature and volume of the contents in this scenario. The increase in temperature and decrease in volume of the contents can be explained by the increase in kinetic energy and decrease in potential energy, respectively. Overall, this comparison highlights the interplay between temperature, energy, and volume in different states of matter and how they are all interconnected.
