if a thermal conductor is exposed to a source of heat, then thermal conduction will make the thermal conductor become hot
thermals is rising_currents_of_warm_air. heat is what_makes_hot. heat_sink is not conductor. heat_sink is conductor. temperature is measure_of_thermal_energy. thermal_conductivity is not tangible_physical_quantity. radiators_and_fires is both_sources_of_heat. temperature is not measure_of_thermal_energy. thermals is not rising_currents_of_warm_air. copper is not good_conductor_of_heat.
