Energy: Forms, Transformation, Transfer, and Conservation
Item NG026004: While a student holds a cold piece of metal in her hand, the metal will get warmer because thermal energy is transferred from warm objects to cold objects when the objects are touching each other.
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 or colder and why?
- Colder, because all objects give off energy all the time and gradually cool down
- Warmer, because some energy is transferred from cold objects to warm objects when the objects are touching each other
- Warmer, because some energy is transferred from warm objects to cold objects when the objects are touching each other
- Neither, because an equal amount of energy is exchanged between warm objects and cold objects when the objects are touching each other
