Question

Who found out the various contents in atmosphere?

• A. Helmholtz
• B. Paracelus
• C. Galan
• D. Andreas Vesaleus

Answer 1

Answer:

A. Helmholtz

The discovery of the various contents in the atmosphere is attributed to several scientists, including:

• Hermann von Helmholtz (1811-1894): A German physicist and physician who made significant contributions to various fields, including the study of the atmosphere. However, his work was more focused on the physics of the atmosphere, including the study of atmospheric electricity and the behavior of gases.

• Other Key Figures:

• Joseph Black (1728-1799): Discovered carbon dioxide.

• Henry Cavendish (1731-1810): Discovered hydrogen and determined the composition of air.

• Daniel Rutherford (1749-1819): Discovered nitrogen.

• Carl Wilhelm Scheele (1742-1786) and Joseph Priestley (1733-1804): Independently discovered oxygen.

• John Tyndall (1820-1893): Contributed to the understanding of the absorptive power of gases in the atmosphere.

Helmholtz's contributions to physics and the study of the atmosphere were significant, but the discovery of specific atmospheric contents is attributed to the collective work of these scientists over the centuries.
