Heat \Heat\, n. [OE. hete, h[91]te, AS. h[?]tu, h[?]to, fr.       h[be]t hot; akin to OHG. heizi heat, Dan. hede, Sw. hetta.       See {Hot}.]       1. A force in nature which is recognized in various effects,             but especially in the phenomena of fusion and evaporation,             and which, as manifested in fire, the sun's rays,             mechanical action, chemical combination, etc., becomes             directly known to us through the sense of feeling. In its             nature heat is a mode if motion, being in general a form             of molecular disturbance or vibration. It was formerly             supposed to be a subtile, imponderable fluid, to which was             given the name caloric.          Note: As affecting the human body, heat produces different                sensations, which are called by different names, as                heat or sensible heat, warmth, cold, etc., according to                its degree or amount relatively to the normal                temperature of the body.          2. The sensation caused by the force or influence of heat             when excessive, or above that which is normal to the human             body; the bodily feeling experienced on exposure to fire,             the sun's rays, etc.; the reverse of cold.          3. High temperature, as distinguished from low temperature,             or cold; as, the heat of summer and the cold of winter;             heat of the skin or body in fever, etc.                         Else how had the world . . . Avoided pinching cold                      and scorching heat!                           --Milton.          4. Indication of high temperature; appearance, condition, or             color of a body, as indicating its temperature; redness;             high color; flush; degree of temperature to which             something is heated, as indicated by appearance,             condition, or otherwise.                         It has raised . . . heats in their faces. --Addison.                         The heats smiths take of their iron are a blood-red                      heat, a white-flame heat, and a sparking or welding                      heat.                                                --Moxon.          5. A single complete operation of heating, as at a forge or             in a furnace; as, to make a horseshoe in a certain number             of heats.          6. A violent action unintermitted; a single effort; a single             course in a race that consists of two or more courses; as,             he won two heats out of three.                         Many causes . . . for refreshment betwixt the heats.                                                                               --Dryden.                         [He] struck off at one heat the matchless tale of                      [bd]Tam o'Shanter.[b8]                        --J.

[bd]The heat of their division.[b8] --Shak.          8. Agitation of mind; inflammation or excitement;             exasperation. [bd]The head and hurry of his rage.[b8]             --South.          9. Animation, as in discourse; ardor; fervency.                         With all the strength and heat of eloquence.                                                                               --Addison.          10.

The             atomic heat of all solid elements is nearly a constant,             the mean value being 6.4.          {Dynamical theory of heat}, that theory of heat which assumes             it to be, not a peculiar kind of matter, but a peculiar             motion of the ultimate particles of matter.          {Heat engine}, any apparatus by which a heated substance, as             a heated fluid, is made to perform work by giving motion             to mechanism, as a hot-air engine, or a steam engine.          {Heat producers}. (Physiol.) See under {Food}.          {Heat rays}, a term formerly applied to the rays near the red             end of the spectrum, whether within or beyond the visible             spectrum.          {Heat weight} (Mech.), the product of any quantity of heat by             the mechanical equivalent of heat divided by the absolute             temperature; -- called also {thermodynamic function}, and             {entropy}.          {Mechanical equivalent of heat}. See under {Equivalent}.          {Specific heat of a substance} (at any temperature), the             number of units of heat required to raise the temperature             of a unit mass of the substance at that temperature one             degree.          {Unit of heat}, the quantity of heat required to raise, by             one degree, the temperature of a unit mass of water,             initially at a certain standard temperature. The             temperature usually employed is that of 0[deg] Centigrade,             or 32[deg] Fahrenheit.

Acid \Ac"id\, n.       1. A sour substance.          2. (Chem.) One of a class of compounds, generally but not             always distinguished by their sour taste, solubility in             water, and reddening of vegetable blue or violet colors.             They are also characterized by the power of destroying the             distinctive properties of alkalies or bases, combining             with them to form salts, at the same time losing their own             peculiar properties. They all contain hydrogen, united             with a more negative element or radical, either alone, or             more generally with oxygen, and take their names from this             negative element or radical. Those which contain no oxygen             are sometimes called {hydracids} in distinction from the             others which are called {oxygen acids} or {oxacids}.          Note: In certain cases, sulphur, selenium, or tellurium may                take the place of oxygen, and the corresponding                compounds are called respectively {sulphur acids} or                {sulphacids}, {selenium acids}, or {tellurium acids}.                When the hydrogen of an acid is replaced by a positive                element or radical, a salt is formed, and hence acids                are sometimes named as salts of hydrogen; as hydrogen                nitrate for nitric acid, hydrogen sulphate for                sulphuric acid, etc. In the old chemistry the name acid                was applied to the oxides of the negative or                nonmetallic elements, now sometimes called anhydrides.

Head-dress       Not in common use among the Hebrews. It is first mentioned in       Ex. 28:40 (A.V., "bonnets;" R.V., "head-tires"). It was used       especially for purposes of ornament (Job 29:14; Isa. 3:23;       62:3). The Hebrew word here used, _tsaniph_, properly means a       turban, folds of linen wound round the head. The Hebrew word       _peer_, used in Isa. 61:3, there rendered "beauty" (A.V.) and       "garland" (R.V.), is a head-dress or turban worn by females       (Isa. 3: 20, "bonnets"), priests (Ex. 39:28), a bridegroom (Isa.       61:10, "ornament;" R.V., "garland"). Ezek. 16:10 and Jonah 2:5       are to be understood of the turban wrapped round the head. The       Hebrew _shebisim_ (Isa. 3:18), in the Authorized Version       rendered "cauls," and marg. "networks," denotes probably a kind       of netted head-dress. The "horn" (Heb. keren) mentioned in 1       Sam. 2:1 is the head-dress called by the Druses of Mount Lebanon       the tantura.
