Why are fires hot and bright?

Why Fire Is Hot. In a nutshell: Fire is hot because it releases more energy than it needs to start the chemical reaction. The excess energy maintains the reaction, converting stored energy in fuel into heat and light.

Is fire just really hot air?

It occurs between oxygen in the air and some sort of fuel. The products from the chemical reaction are completely different from the starting material. The fuel must be heated to its ignition temperature for combustion to occur. The reaction will keep going as long as there is enough heat, fuel and oxygen.

Can black fire exist?

This is black fire. When you mix a sodium street light or low-pressure sodium lamp with a flame, you'll see a dark flame thanks to the sodium and some excited electrons. “It's strange to think of a flame as dark because as we know flames give out light, but the sodium is absorbing the light from the lamp.

Is lava hotter than fire?

While lava can be as hot as 2200 F, some flames can be much hotter, such as 3600 F or more, while a candle flame can be as low as 1800 F. Lava is hotter than a typical wood or coal-buring fire, but some flames, such as that of an acetylene torch, is hotter than lava.

Is green fire real?

Copper Sulfate Green Fire

Sprinkle solid copper sulfate onto a fire to impart a green flame. Copper sulfate dissolves in rubbing alcohol and produces pure green fire. The copper compound is not consumed by the fire, so adding more fuel maintains the color.
