You can’t burn pure water, which is why we use it to put out fires instead of starting them. You can, however, break it down into hydrogen and oxygen by putting energy into it, in the form of an electric current.
How can there be fire under water?
The oxidizer is the oxygen in the surrounding atmosphere. These two ingredients can sustain a candle flame. In the case of an underwater torch, both the combustible substance and the oxidizer must be supplied by hoses leading down to the torch, since no free oxygen is available underwater.
Can there be fire in space?
Fires can’t start in space itself because there is no oxygen – or indeed anything else – in a vacuum. Yet inside the confines of spacecraft, and freed from gravity, flames behave in strange and beautiful ways. They burn at cooler temperatures, in unfamiliar shapes and are powered by unusual chemistry.
Is making napalm illegal?
Napalm is legal to use on the battlefield under international law. Its use against “concentrations of civilians” is a war crime.
Is napalm banned?
The United Nations banned napalm usage against civilian targets in 1980, but this has not stopped its use in many conflicts around the world. Although the use of traditional napalm has generally ceased, modern variants are deployed, allowing some countries to assert that they do not use “napalm.”
Why does your head explode in space?
Oxygen in the rest of your body will also expand. You’ll balloon up to twice your normal size, but you won’t explode. Without air in your lungs, blood will stop sending oxygen to your brain. You’ll pass out after about 15 seconds.
Does fire absorb oxygen?
Air contains about 21 percent oxygen, and most fires require at least 16 percent oxygen content to burn. Oxygen supports the chemical processes that occur during fire. When fuel burns, it reacts with oxygen from the surrounding air, releasing heat and generating combustion products (gases, smoke, embers, etc.).
Can a civilian own a claymore?
The United States first produced Claymore mines in 1960 and has since produced 7.8 million of them for a cost of $122 million. When used in command-detonated mode, Claymores are permissible under the Mine Ban Treaty. When used in victim-activated mode, usually with a tripwire, they are prohibited.
What can burn underwater?
Sparklers can burn underwater, but the metal flame is much hotter than flame from a match, and even then, it has to be wrapped in tape to limit the amount of water that’s in contact with it. So even if you saturated the water with enough oxygen to sustain combustion, I highly doubt that you can ignite anything in the water.
How does a fire burn in the water?
So I know that if you provide an oxygen source fire can burn underwater, either by providing enough heat tthat the water breaks down and provides the oxygen or via some other chemical or mechanical means.
How would it be possible for fire to exist underwater?
Magnesium is one of these and if pure enough will actually ignite upon contact with water. If an underwater earthquake were to expose a vein of reasonably pure magnesium it would ignite and burn intensely until all of the magnesium were consumed.
