Question 1 of 10
1. Question
Approximately how much denser is the air a diver breathes at a depth of 30 meters/99 feet as compared to the surface?
Correct
Incorrect
For every 10 meters/33 feet of sea water, add 1 atmosphere of pressure. Then add the one atmosphere we start with. At 30 m/99 feet, that’s a total of four atmospheres of pressure. To fill the same volume (your lungs), you need four times as much air, so the air will be four times as dense.
