  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.

  4. As,the metals are good conductors of heat,metals can gain heat by the process of conduction .So,tge cup with metal spoon will cool down faster as the metal spoon (being lower at temperature) will gain heat from the hot coffee (being at higher temperature) through conduction of heat due to colliding of faster moving molecules of hot coffee with slower moving molecules of metal spoon.
