It is assumed that non-saturated vapors are subject to the same laws as gases.
APPLICATIONS. CORRECTION OF THE BOILING-POINT IN THE CONSTRUCTION OF THERMOMETERS. BAROMETRICAL THERMOMETERS.
Lessons 14–16. Various Applications of the Laws previously established.
A phenomenon can not always be separated from the accessory phenomena which concur with it in producing the final result. Necessity of corrections to render complex results comparable inter se.
Density of solids when regard is had to the temperature and weight of the gases displaced by them.
Precautions to be attended to in the experiments. Empirical formulæ for the density of liquids. Maximum density of water. The temperature corresponding to the maximum must be determined graphically, or by interpolation.
Corrections for measures of capacity, for barometric measures.
The uncertainty of the corrections can not, in any considerable degree, affect the densities of solids and liquids.
Density of gases. Biot and Arago’s experiments. Special difficulties of the question. The uncertainty of the corrections may sensibly affect the results. Regnault’s method.
The same method may be applied to the determination of the co-efficient of dilatation for gases.
