@telepathyavos37864 жыл бұрын
This video is quite confusing. It first says that the bonds between the atoms do not break, instead, the intermolecular forces break. This was said in the part about simple covalent structures. However, for the giant covalent structures, he states that the covalent bonds will have to be broken, instead of the intermolecular forces.
@Cognitoedu4 жыл бұрын
Hi there - yeah that is the main confusing point in this topic. For simple molecular substances it's the intermolecular forces (weak forces between the molecules) that need to break to melt the substance. Whereas for giant covalent structures (like diamond), it's the strong covalent bonds that have to be broken.
