# Question: In his original barometer Pascal used water instead of mercury

In his original barometer, Pascal used water instead of mercury.

(a) Water is less dense than mercury, so the water barometer would have (1) a higher height than, (2) a lower height than, or (3) the same height as the mercury barometer. Why?

(b) How high would the water column have been?
