hi
so this might be a really dumb question but im so confused.
diamond has a high melting point right? apparently this is because carbon atoms in diamond are bonded covalently, so require a lot of energy to overcome. but i thought that when a substance changes state, the intermolecular forces weaken? the molecules themselves don't come apart, like when water evaporates the hydrogen and oxygen dont split?
why do the bonds within molecules in diamond weaken/break rather than the intermolecular forces weakening?
