One of the underlying problems that led to the discovery of atmospheric pressure was:
A) Why barometers work better on mountain tops than they do in valleys.
B) Why vacuum pumps were more effective than siphons.
C) Why it is harder to open a wine barrel in the winter than in the summer.
D) Why siphons would not work beyond certain height limitations.
E) Why fermentation occurs more rapidly in sealed containers than in open containers.

Question

Quizplus · Accepted Answer

Observations showed that siphons could only draw water up to a certain height before they would fail to work. This led to the realization that there must be a limit to the upward pressure that could be created by the weight of the water alone. Eventually, this understanding led to the discovery of atmospheric pressure.
