Can you melt wood?
gpt
Wood will pyrolyse or thermally decompose into simpler organic (carbon based) molecules. These are given off predominantly as gases. As this happens you gradually get a more carbon rich solid; charcoal. So no it doesn't melt. Even further and you'd end up with something you could probably call carbon which would then melt at 3550 degrees C. 

The point is, wood is a complicated material both structurally and compositionally. So trying to apply to it an understanding of the effects temperature has on materials that is normally used for simpler materials (such as the elements) doesn't work. Wood is not made up of lots of indistinguishable hard spheres and so it won't have a simple phase diagram that nicely transitions to solid, liquid or gas.
