What the density of sea water at depth of 1000 M where the water pressure is about 1.0*10^7 pascal the density of sea water at the surface is 1.03*10^3 kilograms per cubic M? 2. Relevant equations BULK MODULUS=dP/dV/V p=pressure v=volume B of water=,21*10^10 n/m^2 it is approx to the bulk of sea water 3. The attempt at a solution Ihave used the (1000m)depth as aforce at the bottom then A=f/p=1000/1.0*10^7=10^-4 M^2 dV=A*h=10^-4*1000=10^-1 m^3 from bulk modulus=dp/dv/v=,21*10^10=10^7/dv/v then dv/v=4,76*10^-3 then v(surface)= x then density surface=mass/v then mass = x then v depth = dv+v surface(because as account to the bulk modulus the volume smaller at the depth) then the density of the depth= mass/v depth it right to assume that the depth is aforce??????
