Depth of sea is maximum at Mariana Trench in West Pacific Ocean. Trench has a maximum depth of about `11km`. At bottom of trench water column above it exerts `1000 atm `pressure. Percentage change in density of sea water at such depth will be around
(Given , B `= 2xx10^(9) Nm^(-2) and P_(atm) = 1xx10^(5 Nm^(-2)))`
