Liquids
The state of matter in which molecules can move freely and conform to the shape of the container but remain attracted to each other
liquid state
V1/T1 = V2/T2
Charles's law
This device measures altitude
altimeter
According to this person, an object immersed in water appears to lose its weight
Archimedes
The fluid friction that tends to slow an object as it moves through a fluid
drag
The attractive force between unlike molecules
adhesion
This law states that temperature and pressure are directly related when volume is held constant
Amontons's law
The device that uses an airtight metal box with thin, flexible walls to measure pressure
aneroid barometer
An upward force exerted by a fluid on a solid object placed in the fluid
buoyancy
The science of shaping objects to allow the smooth flow of fluids around them and reduce drag
streamlining
The phenomenon in which a liquid in thin tubes rises above or falls beneath its own level
capillarity
The ability of a gas to be easily squeezed and compacted into smaller containers
compressibility
P1V1 = P2V2
Boyle's law
This principle states that the buoyant force experienced by an object is exactly equal to the weight of the fluid displaced
Archimedes' principle
The force on an object that is generated by relative motion between the object and a fluid and is perpendicular to the direction of fluid flow
lift
SI unit of pressure
pascal
This law states that if the pressure of a gas is constant, its volume and temperature are directly proportional
Charles's law
Finput/Ainput = Foutput/Aoutput
Pascal's principle
The condition at which a submarine is completely underwater but not sinking
neutral buoyancy
The phenomenon of a spinning cylinder or ball causing lift
Magnus
The force exerted per unit of area
pressure
P1/T1 = P2T2
Amontons's law
This happens to atmospheric pressure as altitude increases
decreases
This technique uses Archimedes' principle to determine the specific gravity of a solid denser than water
hydrostatic weighing
The angle of the foil relative to fluid flow
angle of attack
