Do you know explosive that does not generate heat?

Question

I need to make an explosion but with out increasing the outside temperature

Answer 1

explosion? What kind of reaction are you initiating? I suppose an explosion of a gas that is cold can happen if the container it's in "explodes" due to too much pressure. (i.e. a balloon popping). A pressue explosion as opposed to a fiery explosion

Answer 2

It really depends on what you need to explode. There is a theoretical endothermic reaction called "cold fusion" but it's not exactly real, you know what I'm saying? Most explosions create heat as a product becasue eneregy is required in making reactions. A simple baking soda and vinegar explostion can be done but it's not really a strong explosion. Many liquids under pressure will explode as well. For example, the soda you drink everyday. Many gases will combust under pressure also. An example is when you take a plastic bag, fill it with air, and compress it. Now you just have to take the basics and use it for your purpose. I probably didn't help you too much but hopefully. One more thing, if you already have a substance, such as water, at a high temperature, if you add a cataylst, like table salt a small explosion-like reaction occurs. You'll just have to do your own research I guess if none of this helps you. Good Luck with that explosion.

Answer 3

Any explosion will increase the political temperature LOL

Consider what an explosive is: It is a relatively small volume of substance that when activated, rapidly produces a large volume of substance; (the latter is usually hot gases).

If it is a chemical explosive, it is almost sure to be exothermic (meaning producing heat). The heat is necessary to speed up the chemical reaction (10 degrees Centigrade doubles a reaction rate generally). The heat is also necessary to heat the resultant gas (Hot gases have greater volume than cool gases)

Perhaps a cylinder of compressed gas being caused to rupture could be considered an explosive. The heat of the chemical charge to rupture the steel tank might be negated by the cooling effect of the expanding gas--perhaps CO-2 might be the gas of choice.

Answer 4

The action of an explosion generates its own heat through friction of particles and rapid expansion. I don't think that is possible without special conditions.

Answer 5

I believe that question violates the definition of explosion.

Answer 6

Alcohols burn and don not produce heat. I have heard eyewitness accounts of people at drag races TOUCHING an alcohol powered engine right after a race. They said the engine was COLD!

Answer 7

Um.. define explosive then.

Answer 8

TRY LIQUID NITROGEN, IT HAS AN EXPANSION RATIO OF ABOUT 10000 TO ONE AND SURELY WOULD NOT CREATE A LOT OF HEAT.EXPENSIVE THOUGH!

Answer 9

no
