| Bunsen's solubility coefficient | The milliliters of gas STPD dissolved per milliliter of liquid and per atmosphere (760 mm Hg) partial pressure of the gas at any given temperature. (05 Mar 2000) |
| Bunsen, Robert | <person> German chemist and physicist, 1811-1899. See: Bunsen burner, Bunsen's solubility coefficient, Bunsen-Roscoe law. (05 Mar 2000) |
| Bunsen-Roscoe law | In two photochemical reactions, e.g., the darkening of a photographic plate or film, if the product of the intensity of illumination and the time of exposure are equal, the quantities of chemical material undergoing change will be equal; the retina for short periods of exposure obeys this law. Synonym: reciprocity law, Roscoe-Bunsen law. (05 Mar 2000) |
