Evangelista Torricelli , “Pressure Barometer”, 1643 was an invention by the Italian scientist for the study of gas-phase, vapors; and, was the topic of an earlier blog post.
- Air in the atmosphere, is seventy-nine (78%) percent molecular nitrogen (N2); plus , twenty-one (21%) percent molecular oxygen (O2); and, one (1%) percent argon (Ar).
Nitrous oxide (laughing gas) can be synthesized from molecular nitrogen & molecular oxygen. This means that H. G. Wells book #2 & book#3 of the volume (221 pages) is a plot one can believe of the Comet.
BELOW is the increasing atmospheric carbon dioxide level (units are “ppm”) from 1958-2017.
