- Yes, the piece of metal will get warmer because some thermal energy is transferred from the metal to the student’s hand.
- Yes, the piece of metal will get warmer because some thermal energy is transferred from the student’s hand to the metal.
- No, the piece of metal will stay at the same temperature because an equal amount of thermal energy is exchanged between the student’s hand and the metal.
- No, the piece of metal will stay at the same temperature because thermal energy is not transferred between the student’s hand and the metal.
