50 Points! I need a thorough response to this assignment. Please do not answer without a correct well written explanation! Thank you! :)
If a diver inhales from their air tank on surface level, the pressure in their lungs will be at 1 atm. If they inhale air from their tank at a depth of 70 m (~230 ft), the pressure in their lungs will be 8 atm. (for every 10 meters below the water, pressure increases
by 1 atm). Assume the diver's lung volume is 1 L. If a diver at 70 m has 1 L of air at a pressure of 8 atm in her lungs and ascends to the surface (1 atm) while holding her breath, what happens to the diver’s lungs? (FYI: total lung capacity is 6.0 L)
Explain what is going on, in a molecular level inside the diver’s lungs, in terms of collisions, volume, and pressure.
