Lack of O2.
The method by which a flame is saved from extinguishing.
A flame arrestor is designed to prevent flames from propagating back into a vessel or pipeline where flammable gases or vapors are present. It works by disrupting the flame's path and extinguishing it to prevent a potential explosion.

I think it is caused by the air causing the flame to keep eating at whatever is combustible. Like blowing on a wick to cause the flame to grow.
There are several reasons why a pilot light could be going on. One reason is there could be a light breeze that is extinguishing the flame.
Striking a match is a physical change because it can be reversed by extinguishing the flame. The chemical composition of the match does not change during this process.
A candle requires oxygen to burn, and when placed in a sealed jar, the oxygen supply is depleted, leading to the candle extinguishing. This happens because the flame consumes the available oxygen, creating a vacuum that eventually snuffs out the flame.
When a glass is placed over a candle, the candle flame burns up the available oxygen inside the glass. As the oxygen is used up, the flame is starved of oxygen and eventually goes out. This demonstrates the concept of oxygen depletion leading to extinguishing of the flame.
The color of the flame depends on the temperature, fuel nature, composition of particles in the flame, oxygen concentration.
The function of a Bunsen burner sleeve is to control the air flow into the burner, allowing for better regulation of the flame temperature and shape. It also helps to protect the flame from drafts and reduces the risk of accidental extinguishing.
Sprinkling charcoal in a flame will cause the flame to change colors. This is apparent in fireworks displays, which routinely use charcoal.
A lighted candle gets extinguished when covered because it is deprived of oxygen, which is necessary for combustion. The flame consumes the available oxygen in the enclosed space, and as the oxygen levels drop, the flame eventually can no longer sustain itself and goes out. Additionally, the buildup of carbon dioxide from the burning wick can also contribute to extinguishing the flame.
