  1. Both cups will be cooler in a few minutes. The one with the metal spoon will cool faster (more) than the one without the spoon.

  2. metals are the good conductor of heat. hence, metals can gain heat by contact. so, the cup with the metal spoon will cool faster.

  3. A tile floor may feel uncomfortably cold to your bare feet, but a carpeted floor in an adjoining room at the same temperature feels warm. Why?
