A marine biologist may need to dive deep underwater for her research. To do so, she may want to know how to do calculations related to pressure and volume changes that occur, depending on the depth of the dive. Suppose she inhales air at a depth of 60 meters and at a pressure of 6 atm. Holding her breath, the marine biologist then ascends to a depth of 10 meters (where the pressure is now 2 atm). What volume would the air in her lungs expand to?
