An adult human lungs can only hold a volume of up to 6.0 L of air when fully expanded. Suppose that at sea level where the pressure is 1.00 atm, a sky diver traps 3.0 L of air in her lungs and holds her breath before rapidly ascending to an altitude where the pressure drops to 0.46 atm. If she doesn't exhale, determine if her lungs will rupture at this high altitude, then complete the sentence:
