How can a star burn without oxygen?
Stars do not require oxygen to “burn” as they produce energy by way of nuclear fusion, gravity rather than oxygen is what keeps it going.
Can fire burn with something other than oxygen?
Can a fire burn in a room with no 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).
What will happen to a fire in an open surrounding where oxygen is plenty?
The flame ignites gases being emitted, and the fire spreads. As long as there is enough fuel and oxygen, the fire keeps burning. Fuel + oxygen (from the air) = combustion products (mainly CO2 + H2O) + heat energy.
Is oxygen necessary for fire?
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.).
What actually burns in a fire?
The actual flames of the fire are the release of some of the heat energy as light. These components have led to the development of the ‘fire triangle’ of fuel, oxygen and heat. Remove any one of these and fire cannot sustain itself.
When you think about combustion think about the fire triangle?
What is the Fire Triangle? The fire triangle, or combustion triangle, is the three components needed to ignite and sustain a fire. The three ingredients of a fire triangle are; heat, fuel and oxygen.
What makes up a fire triangle?
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 the ocean catch fire?
Over the weekend the world watched in horror as the ocean caught fire. A gas leak from a ruptured pipeline in the Gulf of Mexico fuelled a huge blaze which raged for five hours on the sea surface. Pemex said a lightning storm ignited a gas leak from an underwater pipeline.
