Bizzare question about explosives! [Don't worry, I'm not trying to make a bomb! See below.]?

I understand the basics of your question, but let me restate them incase I missed something:

If an explosive device was sealed in an impenetrable structure with no airspace and detonated, would it explode? (or how well would it explode)..

Basically, it'd pressurise itself as it exploded, and thereby only partially explode (assumee it didn't need oxygen in it's reaction). The pressurization would equalize immediately afterwards, perhaps in-time to detonate as a secondary explosion, but I doubt it. The explosive force would be minimized though because there's no "weak spot" for the explosion to flow towards.

Or at least that's my best estimate, based on experience and my understanding of your question.

More than likely you would have a pressurized room waiting to expell like gas in a propane tank. The force is gone, but now you have expansion of molecules. Depending on the type of explosive you use, that is. Powders and non gas explosives would just leave no pressure, and gas explosive and chemical would expand and create pressure.

And the force of the explosion and/or expansion would depend on the amount of oxygen you had in the room, since it takes oxygen to mix with all to burn or expand.

relatively, definite, i think of he's over-reacting. yet then, i'm no longer able to truly criticise as i do no longer comprehend for confident i does no longer over-react if I have been dealing with a similar determination. From what i've got seen, the missiles have not got the variety to realize Hawaii, so does not look a great number of a raffle on the 2nd, and although in the event that they did that's via no ability particular that North Korea is bored to death in latest and desires to influence the U. S.. Come on, after what handed off to the jap after Pearl Harbor you may think of human beings might have learnt the lesson...

Most explosives react even more rapidly under pressure. The reaction would complete and you would have a VERY high pressure area in the casing.

yeah im guessing it should be able to because the explosive force from the bomb, would force dents in the container but would not destroy it.
