Everything outside of the boundary is considered the surrounding… Thermodynamics: Spontaneity, Entropy, and Free Energy. For example, if the system is one mole of a gas in a container, then the boundary is simply the inner wall of the container itself. THE THIRD LAW OF THERMODYNAMICS1 In sharp contrast to the first two laws, the third law of thermodynamics can be characterized by diverse expression2, disputed descent, and questioned authority.3 Since first advanced by Nernst4 in 1906 as the Heat Theorem, its thermodynamic status has been controversial; its usefulness, however, is unquestioned. This constant value cannot depend on any other parameters characterizing the closed system, such as pressure or applied magnetic field. The same is true for the magneto- The third law of thermodynamics states that: “The entropy of all the perfect crystalline solids is zeros at absolute zero temperature”.
