Q

A student is holding a cold piece of metal in her hand. While she is holding the piece of metal, her hand gets colder. Does the piece of metal get warmer? Why or why not?

a. Yes, the piece of metal will get warmer because some cold is transferred from the metal to the student’s hand.

b. Yes, the piece of metal will get warmer because some thermal energy is transferred from the student’s hand to the metal.

c. No, the piece of metal will stay at the same temperature because an equal amount of thermal energy and coldness is exchanged between the student’s hand and the metal.

d. No, the piece of metal will stay at the same temperature because neither thermal energy nor coldness is transferred between the student’s hand and the metal.

A

b. Yes, the piece of metal will get warmer because some thermal energy is transferred from the student’s hand to the metal.
