Expert Answer
Melting is a property of a substance which changes from solid state to liquid state without decomposition/combustion. Wood does not melt because it decomposes before its melting point. Wood is mainly made up of long-chain organic molecules such as; cellulose, lignin and water that decompose into products such as charcoal, water, methanol, and carbon dioxide upon heating. All substances that combust have natural temperature after which they does not melt instead chemical reaction takes place.
