Chapter 12, Problem 30SP
In 2010 the U.S. Center for Coastal and Ocean Mapping measured the deepest known point of the Earth’s oceans in the Mariana Trench. It was 10 994 m (36 070 ft) deep, more than a mile taller than Mt. Everest. Compute the gauge pressure at that depth assuming the density of seawater is constant. [Hint: Use Table 12-1.]

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
