The specific heats may be any function of the temperature consistently with the characteristic equation provided that their difference is constant.
Thus The Direct Experimental Evidence Is Somewhat Meagre And Conflicting, But The Question Of The Relation Of The Specific Heats Of Gases Is One Of Great Interest In Connexion With The Kinetic Theory And The Constitution Of The Molecule.
Its ratio of specific heats has very nearly the ideal value 1 666, appropriate to a monatomic molecule.
The extreme frosts and heats of the English climate are unknown, but occasional heavy snow-falls occur, and the sea in shallow inlets is covered with a thin coating of ice.
Trans., 1904, 203 A, p. 139) for those elements whose atomic heats vary considerably with temperature.
The specific heat of indium is o 057; and the atomic heats corresponding to the atomic weights 38, 76 and 114 are 3.2, 4.3, 6.5.
It may be added that helium has the same character as argon in respect of specific heats (Ramsay, Proc. Roy.
It is now known, however, that when weak acids or bases are used, the heat of neutralization may be either greater or less than the normal value for powerful acids and bases, so that there is no proportionality, or even parallelism, between the strengths of acids and their heats of neutralization (see Solutions).
Now we know the heats of formation of carbon dioxide (from diamond) and of liquid water to be 94300 cal.
It is remarkable that the difference in the heats of formation of ketones and the paraffin containing one carbon atom less is 67.94 calories, which is the heat of formation of carbon monoxide at constant volume.
