Understanding Energy and Its Transformations

Energy in Material Systems

A system is an organized set of interacting elements that utilize an energy source and exhibit global properties. A material system is a defined portion of the universe under consideration. The scale of these systems ranges from the universe to submicroscopic particles, spanning astronomical (1021), macroscopic (100), microscopic (10-4), and submicroscopic (10-14) levels.
