effect of temperature difference
81Thermoelectricity — (thermo electricity) refers to a class of phenomena in which a temperature difference creates an electric potential or an electric potential creates a temperature difference. In modern technical usage, the term almost always refers collectively… …
82List of eponymous laws — This list of eponymous laws provides links to articles on laws, adages, and other succinct observations or predictions named after a person. In some cases the person named has coined the law – such as Parkinson s law. In others, the work or… …
83Second law of thermodynamics — The second law of thermodynamics is an expression of the universal law of increasing entropy, stating that the entropy of an isolated system which is not in equilibrium will tend to increase over time, approaching a maximum value at… …
84Precipitation (meteorology) — Long term mean precipitation by month In meteorology, precipitation (also known as one of the classes of hydrometeors, which are atmospheric water phenomena is any product of the condensation of atmospheric water vapor that falls under… …
85Thermopower — The thermopower, or thermoelectric power (also called the Seebeck coefficient) of a material is a measure of the magnitude of an induced thermoelectric voltage in response to a temperature difference across that material. The thermopower has… …
86History of electrochemistry — Electrochemistry, a branch of chemistry, went through several changes during its evolution from early principles related to magnets in the early 16th and 17th centuries, to complex theories involving conductivity, electrical charge and… …
87Crystallization (engineering aspects) — In chemical engineering crystallization occurs in a crystallizer. Crystallization is a unit operation through which a chemical compound, dissolved in a given solvent, precipitates under certain conditions to allow successive separation between… …
88Entropy — This article is about entropy in thermodynamics. For entropy in information theory, see Entropy (information theory). For a comparison of entropy in information theory with entropy in thermodynamics, see Entropy in thermodynamics and information… …
89Heat pump — A heat pump is a machine or device that moves heat from one location (the source ) to another location (the sink or heat sink ), using work. Most heat pump technology moves heat from a low temperature heat source to a higher temperature heat sink …
