which of the following be the best of transferring thermal energy, fiberglass insulation iron, radiator Styrofoam cup, or rubber floor mat

Answer 1

The best of transferring thermal energy would be the radiator, as it is specifically designed to emit heat efficiently. Fiberglass insulation, Styrofoam cup, and rubber floor mat are all materials that are more commonly used for insulation and would not be as effective at transferring thermal energy.
