80 CORK INSULATION sion. If a substance is heated from 0° C. to 1° C, the fraction of its length that the body expands is its cofficient of linear expansion, the fraction of its area that the body expands is its coeffi- lient of superficial expansion and the fraction of its volume that the body expands is its' coefficient of cubical expansion. The expansion of most substances has been found to be nearly constant for each degree of temperature, and it is therefore the practice to determine the mean coefficient for a change of several degrees. If 1^ is the length of an iron bar at temperature t^ and I2 the length at temperature tg, then the expansion in length for 1° C. is expressed by l^li 1,-1, ts—t, t if tj— ti is expressed by t. Now the fraction of its length that a body expands when heated from 0° C. to 1° C. is taken as its coefficient of linear expansion, which shall be designated as a. Therefore, the original length, l^, times the coefficient of linear expansion of the material, a, or 1^ a, must equal the expansion in length for 1° C, or lia= , I2— li U—U or a= , t li t or h^hCl+at); and, similarly, if k is the coefficient of cubical expansion, Vj and V2 the volumes at temperatures t^ and tg, respectively, then V2—Vi Va—Vi k= = , Vi (t:—ti) Vi t or V2=Vi (1+kt). Superficial and cubical expansion for solids are computed from the linear expansion, the coefficient of superficial expansion being twice and the coefficient of cubical expansion being three times the coefficient of linear expansion. 41.—Determination of the Expansion of Substances.—The linear or cubic expansion of a solid may be determined by the actual measurement of its dimensions at different temperatures, or its cubic expansion may be determined indirectly by measuring the volume of the solid at various temperatures by the gravimetric method, in common use by chemists. The determination of the expansion of water and all other i I
HEAT AND THERMAL EXPANSION 81 volatile liquids is attended by difficulties due to the formation of vapor when heated. The most accurate results are obtained by first determining the volume of a glass vessel at each of various temperatures by weighing the vessel full of mercury at those temperatures and then using the vessel to determine the density of the given liquid at the various temperatures. The accompanying table gives the results obtained in this way for water by Edward L. Nichols and William S. Franklin (The Elements of Physics; The MacMillan Co., New York City).

There are perceptible differ- ences of expansion of various gases at equal pressures for a given rise in temperature; carbon dioxide, ammonia and water vapor, for example, being distinctly different from hydrogen, nitrogen and oxygen, disproving the accuracy of Gay-Lussac's law.
