What the heck is Fire?

Sean: Is fire a type of plasma?

Me: Why?

Sean: Because fire is very hot and it can't be a gas because you can see it and you can't see gases.

Me: You mean you can't see gases?

Sean: Yeah, except steam.

Sean: So is fire gas or plasma? What is fire?

Before we get into what fire is, isn't neon a kind of gas, and we can see neon right?


According to the answer to Question No97 here; fire is NOT plasma.
According to the discussion here, fire IS plasma...sigh...

Fire is the result of breaking bonds in carbon based molecules through the addition of heat energy. This reaction releases energy in the form of heat and light.

When Brian gets back from school, I'll get him to check the links out and see if he understands better than I do. Hopefully, he is able to explain better to his didi.

Keeping Sean home today, just because.
