at the waters surface, air exerts 1 atmosphere (atm) of pressure. under water, the pressure increases. The pressure P (atm) varies with depth d(ft) according to the equation P=(d/33)+1. Boyles law says the volume V of air varies inversely with the pressure P. If you hold yur breath the volume of air in your lungs increases as you ascend. when have 4 qt air in lungs at a depth of 66 ft (P=3atm), the air will expand to 6 qt when you reach 33 ft, where P=2atm.

Question

at the waters surface, air exerts 1 atmosphere (atm) of pressure. under water, the pressure increases. The pressure P (atm) varies with depth d(ft) according to the equation P=(d/33)+1. Boyles law says the volume V of air varies inversely with the pressure P. If you hold yur breath the volume of air in your lungs increases as you ascend. when have 4 qt air in  lungs at a depth of 66 ft (P=3atm), the air will expand to 6 qt when you reach 33 ft, where P=2atm.
