Why is it so difficult to breathe when snorkeling at a depth of 1 m and practically impossible at a 2-m depth? Why can’t a diver simply breathe through a hose that extends to the surface?
Solution 25E Step 1 : Lungs act like balloons. The lungs are inflated and as they get into water they get compressed , thus the air in the lung also get compressed. Air pressure in the hose of diver is more than the lungs of the diver, and air does not allow itself to flow from region of lower pressure to higher pressure Lungs are designed for compressing the air and blowing out, they are poor at sucking the air from the hose . Thus the diaphragm in a person’s body reduces lung pressure causing difficulty in breathing. Therefore the diver cannot snorkel at the depth more than 1m
