Not disorderly and random. 2. disorder The 18-19 century, the invention of the steam engine to promote the development of thermal power conversion efficiency and reflect the thermodynamic problems. In the study on the nature of thermal power conversion, people research into the microscopic nature of the material, that the material is composed of a large number of molecules and atoms. The motions of these molecules and atoms are random, accidental, and disorder. (of chaos). Chaos in ancient Greece two things: generation before the original state; or the underworld). 3. directionality of process The thermodynamic processes (gas diffusion, heat conduction, etc.) are all directional and irreversible processes. From microcosmic essence, it is to the direction that disorder increases. Irreversible phenomenon many, such as: the growth of peoples life process is irreversible: today you how can I repeat the story yesterday! With the words of men of literature and writing: deciduous forever, life is old; Spilled water cannot be gathered up.; It passes like this.. 4. entropy (Entropy) 4.1, the purpose of the introduction: unified description of various disorder, directionality. 4.2 introduction history: In 1864, Clausius, a French physicist, proposed the concept of entropy, but it was abstract. In 1872, Austrias greatest physicist, Boltzmann, made a microscopic explanation of entropy in the study of the movement of gases, known as S=k LnW. Afte
