Is become a compound word?
Yes it’s a compound word. Think of words like: cupcake (two separate words with two different means coming together to make an altogether different word), treehouse, doghouse. It’s a verb, that I’m aware of full on.
Can fire exist without oxygen?
A fire cannot burn without oxygen. The burning that a star does, then, is a nuclear reaction, and not a chemical one like the fires on Earth (when a candle burns, the atoms themselves remain unchanged: just the molecules are affected).

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.).
How can we sustain fire?
Keeping a fire burning is a cycle. Start with tinder, then add kindling, and finally wood….Use dry firewood.
- Stay away from recently chopped trees, as they have a lot of water still and won’t contribute to a sustaining fire.
- Seasoned firewood is the best, because it has been left to dry out for months or even years.
Is the sun on fire?
Answer: 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.
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 fire burn underwater?
Originally Answered: Can fire occur underwater? Yes. If you supply fuel and oxidizer. There are also flares that burn underwater.
What is tetrahedron of fire?
A tetrahedron can be described as a pyramid which is a solid having four plane faces. Essentially all four elements must be present for fire to occur, fuel, heat, oxygen, and a chemical chain reaction. Each of the four sides of the fire tetrahedron symbolise the Fuel, Heat, Oxygen and Chemical Chain Reaction.
What is burning without oxygen called?
Incomplete combustion will occur when there is not enough oxygen to allow the fuel to react completely to produce carbon dioxide and water. As is the case with complete combustion, water is produced by incomplete combustion; however, carbon, carbon monoxide, and hydroxide are produced instead of carbon dioxide.
How do you burn in absence of oxygen?
Pyrolysis, which is also the first step in gasification and combustion, occurs in the absence or near absence of oxygen, and it is thus distinct from combustion (burning), which can take place only if sufficient oxygen is present.
