... of a star, since only there the temperature is high enough to maintain the reaction. The material which surrounds the reaction zone can be considered to play the role of a thermal insulator. We thus can decompose the star, albeit somewhat crudely, into two sub-systems: the core or heat source of the ...

... Note that units are Joule per kelvin and the sign is the same as Q since T > 0 • However, the above formula can only be used to calculate the entropy change if the process is reversible.. • To find the entropy for an irreversible process and since state functions only depend on the end points, the t ...

... A01. Assume that the entropy S and the number of states in phase space Ω of a physical system are related through an arbitrary function, S = f (Ω). Show that the additive character of S and the multiplicative character of Ω necessarily require that f (Ω) ∼ ln Ω. A02. Consider mixing of two gases wit ...
