|---|---|
| specific heat capacity | <chemistry> The amount of energy required to raise the temperature of one gram of a substance by one degree Celsius (or Kelvin). (09 Jan 1998) |
| drosophila heat-shock protein | <protein> Proteins which are immediately produced when the Drosophila fruit fly is exposed for a short time to extreme heat or other stress, such as toxic substances or alcohol. (09 Oct 1997) |
| initial heat | The first burst of heat produced after the beginning of a muscle twitch, described by A. V. Hill. (05 Mar 2000) |
| innate heat | In ancient Greek medicine, the heat of the heart sustained by the pneuma and distributed by the arteries throughout the body. (05 Mar 2000) |
| unit of heat | Calorie (gram calorie; kilocalorie) Synonym: British thermal unit. Synonym: joule. (05 Mar 2000) |
| latent heat | The amount of heat that a substance may absorb without an increase in temperature, as in conversion from solid to liquid state (ice to water at 0캜), or from liquid to gaseous state (water to steam at 100캜). Compare: sensible heat. (05 Mar 2000) |
| alveolar point | The most anterior point on the maxillary alveolar process in the midline. Synonym: alveolar point, prostheon. Origin: G. Ntr. Of prosthios, foremost (05 Mar 2000) |
| anterior focal point | The point where parallel rays from the retina are focused. (05 Mar 2000) |
| apophysial point | The centre of the root of the anterior nasal spine. Synonym: apophysary point, apophysial point, spinal point. (05 Mar 2000) |
| arrow point tracing | A tracing of mandibular movements made by means of a device attached to the opposing arches; its shape resembles that of an arrowhead or a Gothic arch, and when the instrument's marking point is at the apex of the arch, the jaws are considered to be in centric relation. Synonym: arrow point tracing, Gothic arch tracing, Gothic arch, stylus tracing. (05 Mar 2000) |
| auricular point | A craniometric point at the centre of the opening of the external acoustic meatus; or, in certain cases, the middle of the upper edge of this opening. Synonym: auricular point. Origin: L. Auricularis, pertaining to the ear (05 Mar 2000) |
| axial point | One of two point's in a compound optical system so related that a ray directed toward the first point will appear to have passed through the second point parallel to its original direction. Synonym: axial point. (05 Mar 2000) |
| boiling point | This is the temperature at which the vapor pressure of a given liquid reaches atmospheric pressure (and thus starts to boil). (09 Oct 1997) |
| boiling point elevation | This is the phenomenon of increasing the temperature at which a liquid boils by dissolving another substance in the liquid (for example: you can raise the temperature at which water boils by adding salt to it). (09 Oct 1997) |
