In the Challenger Deep of the Marianas Trench, the depth of seawater is 10.9 km and the pressure is 1.16×108Pa (about 1.15×103atm). (a) If a cubic meter of water is taken from the surface to this depth, what is the change in its volume? (Normal atmospheric pressure is about 1.0×105Pa. Assume that k for seawater is the same as the freshwater value given in Table) (b) What is the density of seawater at this depth? (At the surface, seawater has a density of 1.03×103kg/m)"
The Mariana Trench is the deepest oceanic trench on earth. Mt. Everest would comfortably fit in its maximum known depth of 36,037 ft. If the atmospheric pressure is 1 atm, and assuming the density of sea water is a constant 1,020 kg/m3 all the way down, what would be the total pressure on a living organism at the bottom of the trench?
1 m = 3.3 ft
a. 1,072 atm
b. 1,077 atm
c. 3,555 atm
d. 3,556 atm
e. 1,078 atm
