Why does something cold, like ice, feel cold on our skin?

We feel cold when we touch an object or matter like ice at a lower temperature than our body temperature. This is because the heat from our body being higher in amount moves to the ice through our skin(by thermal conduction) in order to attain thermal equilibrium between the ice and the body.

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.
