if a thermal conductor is exposed to a source of heat, then thermal conduction will make the thermal conductor become hot
thermal_conductivity is tangible_physical_quantity. thermals is rising_currents_of_warm_air. heat is what_makes_hot. thermal_energy is kinetic_energy. heat_sink is conductor. copper is good_conductor_of_heat. conductress is conductor. radiators_and_fires is both_sources_of_heat. thermal_energy is energy. temperature is measure_of_thermal_energy.
