Admin What happens to carbon during fires?
Fires cause a sudden conversion of stored carbon into CO2, which is released to the atmosphere. The effect of a fire on the carbon balance can last for a number of years, depending on the intensity of the fire and the recovery of the ecosystem.
Why does fire create carbon?
This glowing gas — and not the fuel itself — produces the spooky blue light that appears at the base of a flame. But the atoms don’t stay single long: They quickly bond with oxygen in the air in a process called oxidation. When carbon bonds with oxygen, it produces carbon dioxide — a colorless gas.
How is carbon dioxide used in fire control?
Fire control 1 Carbon dioxide is denser than air and forms a layer around the burning substance.It covers the fire like a blanket due to which fresh air cannot reach the burning substance.The 2 Carbon dioxide gas neither burns itself nor supports burning. 3 It does not harm the electrical equipment.
What happens to carbon dioxide when a tree is burned?
Over the course of a tree’s life it absorbs carbon dioxide from the atmosphere and then releases this carbon dioxide when it either decomposes naturally or is burned. For this reason, no CO2 is added to the atmosphere, it simply releases the carbon dioxide that was previously accumulated back into the environment.
How is the air supply to a burning substance cut off?
The air supply to a burning substance can be cut off in a number of ways such as covering the burning substance with carbon dioxide,sand,blanket or a damp cloth. The electrical fires are extinguished by using carbon dioxide gas fire extinguisher.
What happens to carbon when it is burned?
Other research has concluded that when something is burned, the carbon stored in it is released. When we burn wood, coal and petroleum products we are releasing the sun’s energy that was trapped long ago by photosynthesis. (Kraus, Concepts in Modern Biology) As glucose is burned, it oxidizes creating a new gas called carbon dioxide (CO 2).
