Toasting caramelizes some of the carbohydrates that are in bread. This is a chemical reaction. You can also call it partial decomposition. Melting is a physical change from solid to liquid. Therefore it does not melt.

When bread is toasted there is a chemical change where the protein and the sugars combine to form glucosamine which is the brown color of toast. If you burn it it is then decomposed into carbon and CO2and water is given off in both cases.

It gets tasty ;)
Well, it doesn't melt - that's for sure. Some water evaporates from it, some fibres may decompose, but not in big quantities (unless you've decided to burn yur toasts completely).
And as water evaporates, the distance between particles is decreasing. So toast gets thiner and crunchy

It burns, which is a form of rapid decomposition. Not 100% sure though.

it can decompose if you leave it in too long and you burn it.
