Հարց 26

A metal spoon and a nonmetal handle touch the same hot pan. Which broad material trend best explains why the spoon usually warms faster?

  1. Metals are always more flammable.
  2. Nonmetals create heat from nothing.
  3. Metals usually conduct heat better.Ճիշտ պատասխան
  4. Only nonmetals transfer thermal energy.

Բացատրություն

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.
