Page 18 - ... rise of temperature could be roughly compared in the two cases ; but in order to avoid part, at least, of the initial disturbance, I propose to exhaust the two globes simultaneously (Fig. 8), and have one limb of the gauge in connection with each globe. With the apparatus so arranged, the ultimate difference of level of the liquid in the two limbs of the gauge will indicate the difference of temperature which existed in the two globes at the instant when the expansion was complete. With a water...
Page 137 - The simplest type of chemical reaction is that in which only one substance is undergoing change, and there is practically no back reaction. A reaction in which only one molecule of a single substance is undergoing change, is termed unimolecular reaction, or a reaction of the first order. Unimolecular Reactions — In cases where the reaction is unimolecular, the equation becomes — which on integration gives— = 2-302 Hog 10 a ~ lo g 10(<*-*)~!

Page 44 - the osmotic pressure exerted by any substance in solution is the same as it would exert if present as gas in the same volume as that occupied by the solution, provided that the solution is so dilute that the volume occupied by the solute is negligible in comparison with that occupied by the solvent.
Page 92 - The electrical resistance of a conductor is proportional to its length and inversely proportional to its cross-sectional area.
Page 24 - The relative lowering of vapour pressure is equal to the ratio of the number of molecules of solute and the total number of molecules in the solution.
