Two objects are made of the same material, but Object 1 has less mass than Object 2. If the objects are at the same temperature, which object has less thermal energy and why?
- Object 1 has less thermal energy because it has less mass than Object 2.
- Object 2 has less thermal energy because it has more mass than Object 1.
- Object 1 and Object 2 have the same amount of thermal energy because they are at the same temperature.
- More information is needed to tell which object has less thermal energy.
