There is a pressure change of 1 bar/ata for every 10 metres/33 feet of depth
change. - accurate answers-What is the pressure change for each 10
metres/33 feet of depth change?
As pressure increases, gas volume decreases and gas density increases. -
accurate answers-What is the relationship between pressure and the volume
and density of air?
, weight - accurate answers-Right now, you are under pressure exerted by the
air in the atmosphere that surrounds you. This is actually the __________ of the
air.
weight - accurate answers-Underwater, you're under more pressure because
water also has __________, which combines with the atmosphere's pressure.
one bar (metric) or one atmosphere (imperial — abbreviated ata) - accurate
answers-At sea level the pressure is fairly uniform, and is expressed as...
As depth in water increases, pressure increases. As depth in water decreases,
pressure decreases. - accurate answers-What is the relationship between my
depth in water and the pressure?
10 metres/33 feet - accurate answers-Because water is much denser and
heavier than air, __________ feet exerts the same pressure as the whole
atmosphere.
Pressure increases by one bar/ata for each 10 metres/33 feet you descend (go
down). - accurate answers-How does pressure increase underwater?
Pressure decreases one bar/ata for every 10 metres/33 feet you ascend
(come up). - accurate answers-How does pressure decrease underwater?
1 bar/ata - accurate answers-At 0 metres/feet (sea level), what is the total
pressure?
2 bar/ata — one of air plus one of water - accurate answers-At 10 metres/33
feet, what is the total pressure?
