Fluid: Anything that flows – gas or liquid

Buoyancy
The ability of a fluid (liquid or gas) to exert an upward force on
an object immersed in it – this is called Buoyant Force

The boat displaces enough water to equal weight of boat,
therefor it floats.

Archimedes principle The
buoyant force on an object in a
fluid is equal to the weight of
fluid it displaced by the object

FLUIDS – BEHAVIOR OF LIQUIDS AND GASES

Multiple Select

Fluids are?

• Gas

• Liquid

• Solid

• Plasma

Multiple Choice

• True or False: Density The ability of a fluid (liquid or gas) to exert an upward force on
  an object immersed in it.

• True

• False

Boyle’s Law
As the volume of
the gas
decreases, the
pressure of a gas
increases,
provided the
temperature does
not change.
Ex. weather
balloon

Pascal’s principle
Pressure applied to
a fluid is transmitted
unchanged
throughout the fluid
Ex. squeezing the
end of a tube of
toothpaste

Bernoulli's principle
As the velocity of a
fluid increases, the
pressure exerted by
the fluid decreases
Ex. the design of an
airplane wing

Charles’ Law
As temperature increases, the
volume increases, provided
pressure remains constant.
Ex. Hot air balloon

Pressure – Temperature
Relationship

As temperature increases, the
pressure increases, provided
the volume does not change.
Ex. popping popcorn
