Somebody please check my charts?
Scuba divers must learn about pressure under water. At the water’s surface,
air exerts 1 atmosphere (atm) of pressure. Under water, the pressure increases.
h e pressure P (atm) varies with depth d (ft) according to the equation P=(d/33)+1.
Boyle’s law states that the volume V of air varies inversely with the pressure P.
If you hold your breath, the volume of air in your lungs increases as you ascend.
If you have 4 qt of air in your lungs at a depth of 66 ft (P= 3 atm), the
air will expand to 6 qt when you reach 33 ft, where P = 2 atm.

Best ResponseYou've already chosen the best response.2well your Pressure and volume relation seems okay , since because \[P \alpha \frac{ 1 }{ V }\]

Best ResponseYou've already chosen the best response.2and as the relation says, with increase in depth , pressure increases hence volume should decrease so your, depth and volume relation seems correct :)
