| second law of thermodynamics | <physics> All of the chemical and physical processes in a closed system tend to drive that system toward maximum entropy. Clausius statement: No device can operate in a cycle and allow heat to transfer from a colder body to a hotter body unless other compensating activities are taking place. Kelvin-Planck statement: no device can operate in a constant-temperature cycle and convert the heat it receives into work, unless other other compensating activities are taking place. (09 Oct 1997) |
| thermodynamics | The study of energy and energy flow in closed and open systems. (18 Nov 1997) |
| third law of thermodynamics | <chemistry> The entropy of a perfect crystal at 0 K is zero. (09 Jan 1998) |
| zeroeth law of thermodynamics | <chemistry> Two systems in thermal equilibrium with a third are in thermal equilibrium with each other. (09 Jan 1998) |
| first law of thermodynamics | This law, derived from the principle of conservation of energy, is expressed as E = Q - W, where E is the internal change in energy, Q is the heat the environment transfers into the system, and W is the work the system does. In other words, it means that: The internal energy in a system isolated from other systems remains constant The change in the internal energy of a system that is not isolated is equal to the energy that crosses its boundariesinto or out of other systemsIt can be further extrapolated to mean that despite all the processesgoing on in the universe, the total energy contained in the universeremains constant. (09 Oct 1997) |
| acute chemical pneumonitis | <chest medicine> Inflammation of the lungs which occurs secondary to exposure to a chemical, organic dust, fungus or mould. Chronic exposure can lead to chronic lung changes evident on chest X-ray. Symptoms include cough, fever, shortness of breath and wheezing. See: bird-handler's disease. (27 Sep 1997) |
| mechanico-chemical | Pertaining to, connected with, or dependent upon, both mechanics and chemistry; said especially of those sciences which treat of such phenomena as seem to depend on the laws both of mechanics and chemistry, as electricity and magnetism. Source: Websters Dictionary (01 Mar 1998) |
| chemical | 1. <chemistry> Of or pertaining to, chemistry. 2. A substance composed of chemical elements or obtained by chemical processes. (21 May 1997) |

| chemical bond | The link between two atoms within a molecule. Different types of chemical bonds include hydrogen bonds, covalent bonds, and ionic bonds. (09 Oct 1997) |
