Discussion Overview

The discussion revolves around the theoretical implications of introducing an explosive into a container of water, specifically focusing on the energy required to vaporize the water and the potential consequences for the container and surrounding environment.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant posits that if an explosive releases energy equivalent to that needed to vaporize the water all at once, the water would likely be expelled forcefully, potentially damaging the container and causing significant harm.
  • Another participant questions whether it is possible to vaporize water suddenly without damaging the container, suggesting alternatives to chemical explosives.
  • A suggestion is made that microwaves could be used to achieve rapid vaporization, but concerns are raised about the container's ability to withstand the resulting pressure, leading to potential explosions.
  • A participant shares personal experience with superheating water in a microwave, indicating that while it is possible to achieve high temperatures, it may not be safe or effective in a typical container.
  • There is mention of using a strong closed container to contain overheated water, but uncertainty remains about whether this method would allow for complete vaporization without risk.

Areas of Agreement / Disagreement

Participants express various viewpoints on the feasibility and safety of vaporizing water with a sudden energy release, with no consensus reached on a definitive method that would avoid damaging the container.

Contextual Notes

Limitations include assumptions about the strength of materials, the nature of the explosive, and the conditions under which vaporization occurs. The discussion does not resolve the complexities involved in achieving rapid vaporization without container disruption.

Hello,
I'm trying to figure out what would happen if you put an explosive into a container of water where the explosive released the same amount of energy it would take to vaporize the water in the container. What would happen to the container?
 
Physics news on Phys.org
Normally, the energy required to vaporize the water would be spread out over a fair amount of time, even if you were boiling it at a very high heat.

If you caused all that energy to be expended at one time, I would assume that the water would end up mostly on the ceiling and the container would be inserted into the walls in small pieces except for the parts that were absorbed by your body.

You would then regret having done the experiment.
 
Ok, would there be any way to vaperise water in a container w/ a sudden burst of energy w/out disrupting the container? Maybe w/out a chemical explosive? So there is little expanding non water gasses, just the pure release of energy?

Microwaves. But unless you have an absolutely tiny amount it would require a huge burst. Much more than is safe to be around. And it is unlikely that the container would be able to survive the massive increase in pressure, so you'd still have an explosion, just from steam this time. Even an open container would probably be severely damaged unless it was very sturdy.

I have done this many times with my tea, and had to clean the mircrowave oven afterwards.

The other way is to use a very strong closed container that can stand the pressure, and keeps the overheated water liquid, until you open it. But I'm not sure if you can get all the water to vaporize that way. And it is not a good idea to try this at home,

Ok, thanks everyone, you guys helped. And what I'm thinking about is not something i plan to do at home, its all strictly theoretical.
