nature : countless experience shows that any one of nature in a limited space and time automatic processes (called spontaneous process), you always tend to balance one-way. The so-called one-way process is the reverse of the process will not happen automatically, and that this process is irreversible. This understanding of regularity is the second law of thermodynamics. It has different interpretations : (1) high-temperature heat from a low-temperature objects conveyed objects, but not for the initiative to the contrary transmission, or by Clausius (Clausius), is "impossible to heat energy by way of low-temperature objects pass by the high temperature objects, but not lead to other changes. "(2)" The second kind of perpetual motion machine is impossible to create. " This perpetual motion machine can be a tremendous material from the system (such as the ocean) to absorb heat constantly, and all of its changes to mechanical energy, with no other changes. The second law of thermodynamics for addressing chemical issues, the ability to determine whether a chemical reaction occurred, if occurred, it can conduct to what extent that is balanced production rate was.
