Unformatted text preview: C) = 13 . 534gcm-3 . How does it change with the local acceleration of gravity? 3. (4 points) The ﬁrst measurements of the properties of high–pressure gases were made by Amagat in France in the 1860s. He worked in a mine shaft using a mercury manometer for pressures up to 400 bar (approx 40 MPa). (He actually later improved his design to go to 3200 bar.) Estimate the size of the instrument needed (for 400 bar). If you assume the diameter of the mercury column was 1 cm, what was the weight of the mercury in the instrument?...
