In the Challenger Deep of the Marianas Trench, the depth of seawater is 10.9 km and the pressure is 1.16 x 10^8 Pa.
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 x 10^5 Pa. Assume that for seawater is 1^-11 pa .)
What is the density of seawater at this depth? (At the surface, seawater has a density of 1.3x 10^3 kg/m^3.)
