So if a bond is formed the energy = heat. But if a bond is form with a substance that is volatile, then a flame will be produced.

But if a catalyst is used, we can lower the high activation energy right?

Thanks. Can you give me an example?

This question came into my mind while I was studying chem. It would be helpful if anyone know. Thank you:-)

So what you're saying is electromagnetic wave is simply a configuration that shows the oscillating string, and electromagnetic field shows the movement of the wave?

what do you mean by volatiles?

so are you saying that both are the same?

thank you. Just to make sure. it's the forming of strong bonds that releases energy in term of flame. So when carbon reacts with a low electronegative element, a fire is created?

thanks for all the replies, but what I don't understand was why was oxygen needed in order to start a fire? (sorry, I should be more specific.) Merged post follows: Consecutive posts mergedFrom Mr. Skeptic, I can conclude that it's because oxygen is a type of oxidizers. But doesn't oxidizers help releases electrons from others substances? How does that helps make a fire?

If so, why?

if so, please explains.
