A submarine at the surface contains 40m3 of air at 1.0atm inside a ballast tank whose total capacity is 60m3; the remaining space is filled with seawater (ρ=1030kgm−3). The submarine dives to a depth where the absolute pressure is 4.0atm and temperature remains unchanged. To stay neutrally buoyant, the ballast tank must remain completely filled. Approximately how much additional seawater mass will enter the tank during the dive?
a) 3.00×104kg
b) 1.03×104kg
c) 3.09×104kg
d) 2.75×104kg
