Question

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.

Answer 1

• Using the data in the example above, make a table and graph to
show how the volume of air in your lungs varies with depth.
• Make a table and graph to show how the volume of air in your
lungs varies with pressure.

Answer 2

Depth Volume of Air in Lungs
0 ft 12 qt
33 ft 6 qt
66 ft 4 qt

Answer 3

Pressure Volume of Air in Lungs
1 atm 12 qt
2 atm 6 qt
3 atm 4 qt

Answer 9

well your Pressure and volume relation seems okay , since because \[P \alpha \frac{ 1 }{ V }\]

Answer 10

and as the relation says, with increase in depth , pressure increases hence volume should decrease so your, depth and volume relation seems correct :)

Answer 11

by the way your name scared me because it sounds like freeman, the scientist , Freeman Dyson

Answer 12

thats correct

Thanks for the help, greatly appreciated!
