Conduction — practice question

Thermal energy is transferred rapidly from the hotter parts of a metal to the cooler parts of the metal. Why do metals make good conductors of thermal energy?

  • AElectrons in the metal vibrate about fixed points and quickly pass energy from one electron to the next.
  • BElectrons move quickly from ions in hot regions to ions in cold regions.
  • CProtons in the metal are close together and move quickly from hot to cold regions.
  • DSmall ions of the metal move quickly from hot to cold regions through spaces in the metal lattice.
