Which type of energy is associated with random motion of atoms and molecules in a sample of air?

1. chemical energy

2. electrical energy

3. nuclear energy

4. thermal energy

I think the best answer from the choices listed above is option 4. It is thermal energy that is associated with random motion of atoms and molecules in a sample of air. This is because the average kinetic energy of the molecules are related to temperature which is a driving force for heat transfer to happen. So, it should be thermal energy.
