Who demonstrated that atmospheric pressure decreases with altitude?

The demonstration that atmospheric pressure decreases with altitude is primarily attributed to the work of Torricelli, von Guericke, and Pascal. Evangelista Torricelli, in the 17th century, is often credited with inventing the barometer and conducting experiments that revealed how atmospheric pressure changes with altitude. He showed that as one ascends in the atmosphere, the weight of the air above decreases, thus leading to a decrease in pressure.

Gottfried Wilhelm von Guericke conducted experiments that illustrated the principles of atmospheric pressure, including his famous demonstration with vacuum spheres. Blaise Pascal further built upon Torricelli's findings by verifying that atmospheric pressure decreases with height through various experiments, including those using barometers.

The collective contributions of these scientists helped to establish the foundational principles regarding atmospheric pressure and its variation with altitude.

In contrast, the other groups mentioned in the options are associated with different scientific contributions. Archimedes, Newton, and Boyle focused more on principles of buoyancy, gravitational force, and gas laws, respectively. Einstein, Galileo, and Edison are linked to physics and inventions rather than atmospheric pressure specifically, while Darwin, Faraday, and Curie explored diverse areas such as evolution, electromagnetism, and radioactivity.
