A scuba diver has his lungs filled to half capacity (3 liters)when 10 m below the surface.If the diver holds his breath while quietly rising to the surface,what will the volume of the lungs be (in liters)at the surface? Assume the temperature is the same at all depths.(The density of water is 1.0 *10³ kg/m³. )

According to Boyle's Law (P1V1 = P2V2), the volume of the lungs will increase as the pressure decreases when the diver ascends. At 10 m depth, the pressure is approximately 2 atm (1 atm from the surface and 1 atm from the water). At the surface, the pressure is 1 atm. Therefore, the volume at the surface will be 3 liters * (2 atm / 1 atm) = 6 liters. The closest option is 5.9 liters.
