| - | The energy principle describes how the energy of a system will change as a result of external work and energy exchange due to a temperature difference. It is a scalar principle as it describes how energy is transferred in and out as well as around a system in different forms. | + | **The energy principle describes how the energy of a system will change as a result of external work and energy exchange due to a temperature difference.** It is a scalar principle as it describes how energy is transferred in and out as well as around a system in different forms. |
