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)"
