What is the relationship The deeper you go in water, the more the pressure
between my depth in increases
water and the pressure? Pressure is expressed as the weight of air
What is the relationship As pressure increases, the gas volume decreases
between pressure, and and the gas density increases
the volume and the
density of air?
If I take a volume of air Volume will be 1/ata#
from one depth to Density will be ata#
another depth, how much
will the volume and
density change?
