ELI5 - Does everything have a melting point and a boiling point? If so, what's the melting point of wood?

(Don't worry, I understood particle theory at 5)

Wood is not a single thing, it's a bunch of stuff arranged together to make what we call wood. There's water, carbon, and a whole bunch of other stuff in it. Each of these has its own temperature that it becomes liquid and gas, as well as the temperature it burns at. For some things, the "burn" temperature is lower than the temperature it melts at, or lower than the temperature of the other stuff in the wood.

When wood is heated the stuff in it starts to break down from the heat. The water changes from liquid to gas and other stuff starts to change because of both the heat and the water boiling away. Then some of the stuff in the wood begins to burn because it is higher than its "combustion point" (a fancy way of saying how hot it can get before it burns). The heat released by the stuff beginning to burn raises the temperature even further and other stuff begins to burn.

The biggest reason that wood doesn't melt is really that the stuff that's in it will mostly burn before it melts.
