A diver fills his lungs to 4.0 L at a depth of 20 m. If he rises quickly to the surface with no air released, what volume would the air occupy (litres, one decimal)? Use 10.3 m of water per atmosphere.
Answer:
11.80
Solution:
Pressure at $20 m = 1 + (20) / (10.3) = 2.94 atm . V = 4.0 \times 2.94 = 11.8 L$ .
