which statement best describes the direction of heat flow by conduction between two samples of the same material? heat flows from faster molecules to slower molecules when they are near. heat flows from faster molecules to slower molecules when they collide. heat flows from slower molecules to faster molecules when they are near. heat flows from slower molecules to faster molecules when they collide.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
