Correct. Van der Waals
and London forces are weak molecular bonds tending to hold substances together as solids or liquids. Increasing motion of molecules due to raised temperature strains against these forces. Total breaking of the forces causes the substance to melt or boil at a specific temperature and pressure. The increase in temperature in a conductor carrying current comes from friction of the electrons passing. Electrons are not electricity, any more than water is pounds per square inch. You cannot bottle a kick up the ass; it's a force not a substance.
Not quite sure why electrical resistance increases with temperature in metals, because it decreases with temperature in carbon.
