The deepest point in the ocean is in the mariana trench, about 11 km deep, in the pacific. the pressure at this depth is huge, about 1.13 3 108 n/m2. (a) calculate the change in volume of 1.00 m3 of seawater carried from the surface to this deepest point. (b) the density of seawater at the surface is 1.03 3 103 kg/m3. find its density at the bottom. (c) explain whether or when it is a good approximation to think of water as incompressible.
