A scuba diver exhales 3.05 L of air while swimming at a depth of 65.10 m where the sum of atmospheric pressure and water pressure is 7.30 atm. By the time this exhaled air rises to the surface, where the pressure is 1.00 atm

✔ 最佳答案
The volume of the air is inversely proportional to the pressure.P1 * V1 = P2 * V2
7.30 * 3.05 = 1 * V
V = 22.265 L
Rounded two three significant digits, the volume is 22.3 liters.

p1*V1 = p2*V2
V2 = V1*p1/p2 = 3.05*7.30/1 = 22.27 liters
V2 = V1*p1/p2 = 3.05*7.30/1 = 22.27 liters
