Explain how the temperature of a substance is related to the kinetic energy of its molecules. every substance is composed of molecules that have kinetic energy. temperature is a measure of the average kinetic energy of molecules in the substance. temperature is measured in units of degrees. as the kinetic energy of molecules increases, temperature also increases, and vice versa.

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.
