Pressure is defined as - ✔️✔️The force per unit area acting on a surface in a direction
perpendicular to that surface
Gas is defined as - ✔️✔️A phase of matter
In the gas phase, the atoms or molecules basically move - ✔️✔️Randomly
Liquids change to a gas at - ✔️✔️their respective boiling points
Hydraulics is a branch of science and engineering concerned with the mechanical
properties of - ✔️✔️Liquids
When applying pressure to a fluid, the pressure is exerted - ✔️✔️In all directions equally
A mechanical gauge is used when measuring gas pressure in a sealed container. For
all common pressure gauges, the pressure indicated on the gauge is - ✔️✔️Less than
absolute pressure because gauges (and gauge pressures) ignore the ambient
(barometric) pressure around us. They ony measure the extra pressure in the container.
Absolute pressure can be defined as - ✔️✔️The amount of pressure within the sealed
vessel + the amount of pressure outside the sealed vessel
Absolute pressure can also be defined as - ✔️✔️Gauge pressure + atmosphere, total
pressure and,true pressure.

1 atmosphere equals - ✔️✔️760 mmHg<br>14.7 psi<br>33 fsw
The barometric pressure in Denver (elevation 5000 ft) is less than barometric pressure
at sea level - ✔️✔️True
To convert from ATA to fsw - ✔️✔️subtract 1, then multiply by 33
To convert ATA to mmHg - ✔️✔️multiply by 760 mmHg
To convert ATA to PSI - ✔️✔️subtract 1, then multiply by 14.7
To convert FSW to ATA - ✔️✔️divide by 33, then add 1
Boyle's law is about the - ✔️✔️pressure-volume relationship
Which gas law has an inversely proportional relationship - ✔️✔️Boyle's law
According to Boyle's law, (assuming the temperature remains constant) when the
pressure increases, the volume - ✔️✔️Decreases proportionally
When applying boyle's Law to the human body, we worry about air-filled spaces being
shrunk (or squeezed) when pressure around the body increases. This particular type of
damage is known as. - ✔️✔️Barotrauma

According to Gay-Lussac's law, the temperature in a rigid container,like a scuba tank or
a hyperbaric chamber, will _______ when the pressure decreases (assuming the
volume remains constant) - ✔️✔️Decrease proportionally
Gay-Lussac's Law (in the hyperbaric chamber) is important to understand because
when we start increasing the pressure in the chamber, the patient is likely to -

GAy-Lussac's Law (in scuba diving) is important to understand because when we start
increasing the pressure in a scuba tank (during a refill at the scuba shop), the tank will
get _____ during the refill_____ while it sits at room temperature. This will cause the
pressure of gas in the cylinder to _______ - ✔️✔️Warmer;cool;decrease

full scuba cyllinder lay in the sun and heat up, the pressure in the tank will _______.
This could potentially cause_____. - ✔️✔️Increase; the scuba cyllinder to rupture
When working mathematical problems involving Charles' law law or Gay-Lussac's law, it
is necessary to convert the temperature from celcius to _____. To do this you _______ -
