Knowledge review 1 - ANSWER- At 10 metres/33 feet you're _____ bar/ata of total pressure and the air density is ___ times as great as at the surface. a. 1 b. 2 c. 3 d. 4 - ANSWER-b. 2 *Pressure increases by one bar/ata for every 10 metres/33 feet of depth. So, at 10 metres/33 feet, the total pressure is 2 bar/ata (one from water pressure and one from atmospheric pressure). Density increases proportionally, so at 2 bar/ata the density is 2 times as great, at 3 bar/ata the density is ...

D float. Salt water is heavier than fresh water because it has dissolved minerals in it. This means it causes more upward force (buoyancy) on an object. An object that is neutrally buoyant in fresh water would float in salt water because there is greater upward force. See Being a Diver I - Buoyancy and Controlling Buoyancy. - ANSWER-1) If an object is neutrally buoyant (does not sink or float) in fresh water, the same object placed into salt water would A sink. B either sink or float....
