How does a flare burn underwater?
The oxidizer is the oxygen in the surrounding atmosphere.
These two ingredients can sustain a candle flame.
The combustible gas, which might be hydrogen or acetylene, depending on the application, can be combined with oxygen gas (the oxidizer) to produce an underwater flame at the tip of the torch..
Why can’t you use ocean water to put out fires?
Ocean water can also be used to fight fires but because salt is corrosive, they have to wash out the aircraft with fresh water afterward, he said.
What animals live in the Ring of Fire?
Explore his Octopus Den and get up-close to fascinating animals like Moon Jellyfish and Japanese Spider Crabs. They all make their home in a constantly changing ecosystem along the Ring of Fire where towering volcanoes and deep ocean trenches line the Pacific Ocean.
What happens if you put fire in water?
Do NOT pour water on the fire! Since oil and water do not mix, pouring water can cause the oil to splash and spread the fire even worse.
Can fire burn 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.
Do flares stay lit underwater?
The flare will extinguish when placed horizontally in water (which is why puddles will extinguish flares) but vertical burning underwater shows that sufficient gas is being generated (as a byproduct of combustion) to displace the water away from the flame front.
Is salt water flammable?
Nope. Common table salt (NaCl) wont burn. It can melt though (sodium=metal). Now, if you took some pure sodium shavings (of the pure metal) and sprinkle them in water, it makes mini fireworks that should never be done at home.
Does napalm burn underwater?
Napalm is basically thick oil or jelly mixed with fuel (petrol, gasoline). … Versions of Napalm B containing white phosphorus will even burn underwater (if there is trapped oxygen in folds of cloth etc.) so jumping into rivers and lakes won’t help those unfortunate souls attacked with this vile weapon.
Can water get hot enough to start a fire?
Superheated steam can get up to and over 451 degrees F hot enough to burn paper, but it only exists at high pressure in an enclose system. Originally Answered: How hot does water have to b before it can ignite a flame? It can’t, because water puts out fire.
Why do grease fires explode with water?
Oil burns at much, much higher temperatures than water boils. … So when you throw water onto a grease fire, the water sinks below the oil and is flash-boiled to steam by the intense heat, which blows the oil out like a small explosion. This causes the oil to break into thousands of tiny droplets.
Can things explode space?
Acute exposure to the vacuum of space: No, you won’t freeze (or explode) … The absence of normal atmospheric pressure (the air pressure found at Earth’s surface) is probably of greater concern than temperature to an individual exposed to the vacuum of space .
Does the sun need oxygen to burn?
The sun does not run out of oxygen for the simple fact that it does not use oxygen to burn. The burning of the sun is not chemical combustion. It is nuclear fusion.
Can there be a fire in the ocean?
The Ring of Fire is home to hundreds of volcanoes. But most remain hidden far below the water’s surface. In fact, seventy-five percent of all volcanic activity on the Earth happens in the ocean. … We’ve only recently begun to explore the hundreds of volcanoes rising from the ocean floor that make up the Ring of Fire.
What type of fire Cannot be put out by water?
APWs are designed for Class A (wood, paper, cloth) fires only. Never use water to extinguish flammable liquid fires. Water is extremely ineffective at extinguishing this type of fire, and you may, in fact, spread the fire if you try to use water on it. Never use water to extinguish an electrical fire.
Why is fire in space bad?
When flames burn on Earth, heated gases rise from the fire, drawing oxygen in and pushing combustion products out. In microgravity, hot gases don’t rise. … Space flames can also burn at a lower temperature and with less oxygen than fires on Earth.
