Page 99 - Elasticity is the name given to "that property by virtue of which a body requires force to change its bulk or shape, and requires a continued application of the force to maintain the change, and springs back when the force is removed ; and if left without the force, does not remain at rest except in its previous bulk and shape.

Page 92 - V is given either by the product of the charge and the potential difference or by one-half the product of the mass of the particle and the square of the final velocity. Solving (6-9) for the velocity, l2eV v = ^ — - meters/sec (6-10) \ in The energy acquired by an electron (e = 1.6 X 10~19 coulomb) in "falling" through a potential difference of 1 volt is 1.6 X 10~19 joule.

Page 70 - Or in different words, the specific gravity of a body is the ratio of its mass to the mass of an equal volume of a standard substance. Specific gravity is thus a numerical ratio, or an abstract number which is independent of the units employed.

Page 70 - The specific gravity or relative density of a substance is the ratio of its density to the density of some standard substance.

Page 68 - P = pressure for absolute temperature t and p' the pressure for t temperature also absolute, then nt P ' or if v be the volume at absolute temperature t and v' at t', then v _t v'~t'' Boyle's law states that the product of the pressure and the volume of a perfect gas remains constant if the temperature of the gas is unchanged, denoting pressure by p and volume by v. Boyle's law is pv = constant. If heat is supplied to a perfect heat engine at absolute temperature T and the absolute temperature of...
