| Found in | Work cat.: The second law of thermodynamics, 1976. McGraw-Hill dictionary of scientific and technical terms, 2003: p. 1882 ("second law of thermodymanics -- (thermo[dynamics]) -- a general statement of the idea that there is a preferred direction for any process; there are many equivalent statements of the law, the best known being those of Clausius and Kelvin") Academic Press dictionary of science and technology, 1992: p. 1942 ("second law of thermodymanics -- thermodynamics -- the general statement that any natural process will tend to proceed in a preferred direction; this is expressed in various forms such as: 1. no device can operate in a cycle and permit a heat transfer from a colder body to a hotter body, unless some other effect takes place (Clausius statement). 2. no device can operate in a constant-tempreature cycle and convert the heat transfer it receives into work, unless some other effect takes place (Kelvin-Planck statement). 3. All spontaneous processes tend to increase the entropy of an isloated system toward a maximum") Chambers dictionary of science and technology, 1999: p. 1162 (under entry, Thermodynamics, "The laws of thermodynamics are: ... (second law) - heat can never pass spontaneously from a body at a lower tempreature to one at a higher tempreature (Clausius), or equivalently, no process is possible whose only result is the abstraction of heat from a single heat reservoir and the performance of an equivalent amount of work (Kelvin - Planck)") |
