Can a gun fire in space?
Fires can’t burn in the oxygen-free vacuum of space, but guns can shoot.
Modern ammunition contains its own oxidizer, a chemical that will trigger the explosion of gunpowder, and thus the firing of a bullet, wherever you are in the universe.
No atmospheric oxygen required..
Can you light a fire in space?
In space, of course, you can’t have any fires because there isn’t any oxidizer (i.e. oxygen) to sustain the combustion process.
Is Sun made of fire?
The Sun does not “burn”, like we think of logs in a fire or paper burning. The Sun glows because it is a very big ball of gas, and a process called nuclear fusion is taking place in its core. … Hydrogen really doesn’t burn, it fuses, into helium. So no oxygen is required!
What are 5 classes of fire?
Fires can be classified in five different ways depending on the agent that fuels them: Class A, Class B, Class C, Class D, and Class K. Each type of fire involves different flammable materials and requires a special approach.
What is the best Defence against fire?
Prevention – Remember prevention is your best defense against fire. the unit to protect the floor from heat and hot coals which might drop out.
Can fire exist without oxygen?
Technically the answer is no. The definition of fire, in the presumed sense of combustion or burning, is “combustion or burning, in which substances combine chemically with oxygen from the air and typically give out bright light, heat, and smoke,” according to Google. So without oxygen it would not be fire.
How does fire burn in space without oxygen?
Without gravity, hot air expands but doesn’t move upward. The flame persists because of the diffusion of oxygen, with random oxygen molecules drifting into the fire. Absent the upward flow of hot air, fires in microgravity are dome-shaped or spherical—and sluggish, thanks to meager oxygen flow.
Does Fire remove oxygen?
Fire does use oxygen when it burns. … Fires use this to produce carbon dioxide by adding a single carbon atom from the fire’s fuel (wood, for instance). So there is just as much carbon dioxide produced as there is oxygen used.
Can hydrogen be burned?
Hydrogen fuel is a zero-emission fuel burned with oxygen. … Since the weight of hydrogen is less than air, it rises in the atmosphere and is therefore rarely found in its pure form, H2. In a flame of pure hydrogen gas, burning in air, the hydrogen (H2) reacts with oxygen (O2) to form water (H2O) and releases energy.
What 3 things does a fire need to burn?
Oxygen, heat, and fuel are frequently referred to as the “fire triangle.” Add in the fourth element, the chemical reaction, and you actually have a fire “tetrahedron.” The important thing to remember is: take any of these four things away, and you will not have a fire or the fire will be extinguished.
Can you burn helium?
Helium is a special gas called a Noble Gas, which means it doesn’t burn. When a match is held near a helium-filled balloon, the balloon pops. That’s it. But when a match is held near a hydrogen-filled balloon: BOOM! a real explosion.
Can a normal car engine run on hydrogen?
This solution is simple, hydrogen engines. There are two types of hydrogen engines. A hydrogen fuel cell engine and a hydrogen internal combustion engine. … Say you have a petrol vehicle and convert it to run on hydrogen, your vehicle will still be able to run on petrol.
What are the 4 stages of a fire?
Compartment fire development can be described as being comprised of four stages: incipient, growth, fully developed and decay (see Figure 1). Flashover is not a stage of development, but simply a rapid transition between the growth and fully developed stages. (see Figures 1 and 2.)
Can fire burn without fuel?
There must be Fuel to burn. There must be Air to supply oxygen. There must be Heat (ignition temperature) to start and continue the combustion process.
Can water put out fire?
Why Does Water Put Out Fire? – Water creates a barrier between the oxygen and the fuel, cooling the fire and removing its heat source. … Water mixing with any electrical circuit that is live can cause a short and spark a fire. Water is a conductor so will not extinguish an electrical fire.
Why are hydrogen engines a bad idea?
They burn clean, and they sound cool, but ultimately they don’t make much sense. Since hydrogen fuel (H2) doesn’t have carbon in it (like gasoline or diesel fuel), there’s no carbon added to the byproducts of combustion in a hydrogen engine. …
What are the 5 stages of fire?
You can see in the image below the intensity of a fire at each stage.Incipient. The incipient stage of a fire is the stage immediately after ignition. … Growth. The growth stage occurs when the fire has established itself and is burning self-sufficiently. … Fully Developed. … Decay.
