1. Evaporation is known to go on more rapidly the warmer
and drier the surrounding air is.

2. The amount of polonium to be obtained from a uranium
mineral can be simply calculated.

3. Gold, the least active metal, is slowly attacked by fused
nitrates and alkali metals, forming aurates, e. g. KAuO2.

4. Hydrogen is far more volatile than oxygen because of
its having a much smaller specific weight.

5. We may suppose the alpha particles within the nucleus
to be in motion.

6. The speed of light being extremely great, we cannot
measure it by ordinary means.

7. The experimental work was done on alkali metal film
reported to be one atom thick.

8. The equivalent weight of radium has been determined
and found to be 113.

9. Except where otherwise expressly stated, the foregoing
values are given in the centimeter — gram — second system
of units.

10. The photoelectrons do not, in general, all succeed in
reaching the anode.

11. To produce a precipitate we must meet two conditions.

12. There is believed to be three distinct oxides of iodine,
their formulae being J2O4, J4O5and JO4

13. Increased temperature makes a gas expand.

14. The potential barrier is too high for electrons to go
through.

15. The alkali metals are remarkable for being so light
as to float on water.

16. Many volumetric determinations depend upon the
oxidation or reduction of the substance to be determined.

17. The isolation of radium followed by many important investigations made on other previously unknown elements proved to be of greatest importance.

18. Water being denser than air, rays are refracted towards
the perpendicular.

19. We may assume the electrons in an atom to revolve
about the nucleus with sufficient velocities to keep them
from being drawn into the nucleus by the attraction of the
positive charge of the nucleus.

20. Unless otherwise specified, the charts and tables are
for a perfect gas with a ratio of specific heats (k) of 1.4.

21. The reason for having the iron in thin laminations
rather than in a solid chunk is to prevent induced currents
being set up in the iron itself, due to the changing flux
through it.

my earlier observation — had made use of the idea of an
elastic ether of such kind as to be able to transmit only
transverse vibrations.

23. Another theory assumes heated gases from the interior
bursting through the crust of the Moon as great bubles.

24. The compounds potassium perchloride and potassium
