  2. Nonmetals create heat from nothing.
  3. Metals usually conduct heat better.Правильный ответ
  4. Only nonmetals transfer thermal energy.

Объяснение

Metals generally transfer thermal energy more effectively than nonmetals, so heat moves along the spoon comparatively quickly. Flammability concerns burning and does not explain conduction from the pan through the material.
