- An aquatic organism needs to be neutrally buoyant to stay at a constant depth. Fish accomplish this with an internal swim bladder they can fill with air that they take in from the water through their gills. One complication is that the pressure in the swim bladder matches that of the surrounding water, but the water pressure changes with depth. Because the volume of a gas is inversely proportional to pressure (as you may already know if you have studied the ideal-gas law), the volume of air in a fish's swim bladder decreases with depth unless the fish actively adds more air.arrow_forwardWhat is the pressure of the gas in the cylinder, in kPa (kiloPascal)? h = 0.620 m, Pmercury = 13,600 kg/m3, 1.0 atm = 1.00 x 105 Pa = 100 kPa, and g = 10.0 m/s?.
