Once the gas forms, combustion occurs as the various molecules react with oxygen to produce the heat and light known as fire.

Are blue flames hotter?

Blue flames aren't always hotter than yellow flames, because the color of light emitted by the flame can depend on exactly which atoms and molecules are in the flame. High-frequency (bluish) light has high energy quanta and low-frequency (reddish) light has lower energy quanta.

What causes orange flame on propane stove?

Orange Flames
An imbalance in the fuel-oxygen mixture can have a variety of causes. Gas burner orifices may become clogged from a buildup of soot, which results in an uneven supply of fuel to the burner. When the flame burns the soot, the resulting incandescence is orange.

Why is a blue flame preferred over a yellow?

Combustion is incomplete and less energy is transferred. A blue flame from a Bunsen burner transfers more energy than a yellow Bunsen flame as complete combustion gives a blue flame. This is because a yellow flame produces a lot of soot.

What Colour gas flame is dangerous?
