WebbIn simple words, the mass of matter in an open system is not fixed and can easily cross the boundaries of the system. Open systems are also known as control volume systems or flow systems. The concept of open, closed, and isolated systems has been derived from the branch of science called thermodynamics. WebbFirst, we have just observed that Δ fG ° and Δ fH ° for the formation of O 2 ( g) “from the elements” is zero at all temperatures because this is just the difference between the G (or H) of oxygen and the G (or H) of the elements making up oxygen, which is the same thing.
