 Pressure is...

the force pushing directly on a given surface.
p=f/a
15A  1 N/m2 =

1 Pascal (Pa)
15A 
1 millibar (mb)=
(metereologists use this term) 
100 Pa (normal atmospheric pressure is 1013 mb)
15A  As you increase the area on which a force acts, the pressure exerted...

decreases.
15A  Ocean water pressure is greater than lake water pressure because...

the salt in the water gives it greater density.
15A  What is the term that describes the study of liquids and gases and the forces they exert?

Fluid mechanics
15A  Pascal's principle...
 Changes in pressure in a confined fluid are distributed equally in all directions throughout the fluid. 15B
 Machines that use fluids to transmit or increase force are...

hydraulic machines.
15B  Mechanical advatage for hydraulics formula...

MA = output force/input force
15B  As blood goes to capillaries, blood pressure...

decreases.
15B  Archimede's principle...

An immersed object is buoyed up by a force equal to the weight of the fluid displaced.
15B  Specific gravity formula...

weight in air divided by weight in airweight in water.
(archimemde's principle)
15B  Bernoulli's principle...
 pressure of a fluid decreases as its speed increases. This allows airplanes to lift off the ground. 15B
 Boyle's Law...

p1v1=p2v2 (pressure and volume are inversely proportional  when one goes up the other goes down)
15C  Charles's Law...

v1/t1=v2/t2
15C
