a metal spoon is placed in one of two indentical cups of hot coffee. Which cup will be cooler after a few minutes?

• physics -

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.

• physics -

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

• physics -

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?
