Item EG048003: For two objects that are made up of the same type of molecule and the same number of molecules, the molecules of the object with more thermal energy have more motion energy.
Object 1 and Object 2 are both made up of the same type of molecule and the same number of molecules. Object 1 has more thermal energy than Object 2. Do the molecules of Object 1 have more, less, or the same amount of motion energy (kinetic energy) than the molecules of Object 2?
- The molecules of Object 1 have more motion energy than the molecules of Object 2.
- The molecules of Object 1 have less motion energy than the molecules of Object 2.
- The molecules of Object 1 have the same amount of motion energy as the molecules of Object 2.
- More information is needed to say anything about the motion energy of the molecules.
