Thermal energy (heat)
The kinetic energy of molecules and is closely related to temperature
Thermal energy (heat)
True/false - the faster the molecules of a substance are vibrating, the more thermal energy the substance has and the higher temperature
True
The energy that is contained within the nucleus of an atom
Nuclear energy
The least familiar form of energy. The type of energy thag is used in x-ray.
Electromagnetic energy (radiation)
