Viscosity
Viscosity is how quick fluids flow
What is density?
How much mass is in one object
What is buoyancy?
The force to push upward
What is compressibility?
Compressibility is when forces act on objects so much that they can deform or crush it.
What is pressure?
The amount of force applied in a given area
What determines viscosity?
Internal resistance or friction
What determines the density?
How big/small the volume or mass is, or the particles it is made out of.
If the buoyancy is higher than density, the object _____
Floats
Why arent liquids compressible?
Liquids cant compress because they have very close particles
Whats pressure measured in?
Pressure is measured in 1 Pa(Pascal), which equals 1 Newton or 100g of force.
If the viscosity is big, is the fluid slow or fast?
Slow
What is the equation for density?
Density = Mass divided by Volume
If the density is bigger than buoyancy, it _____
Sinks
Because theres lots of space between the particles
Whats the equation for pressure?
Pressure = Force divided by Area
If the temperature is high, is the viscosity low or high?
Low
If the temperature is high, is the density big or small?
Small
If the buoyancy is equal to density, the object _____
Stays in the middle
Whats the device that uses compressed air to lift pressure?
Depth
What is the ramp method?
The ramp method is where you use a ramp to determine the viscosity of a liquid by seeing how fast/slow it goes down on the ramp
If a solution is more concentrated, what happens?
Density increases
Whats the plimsoll line?
It is a water line that shows how heavy a ship is for different bodies of water. It also shows if the ship is too heavy and unsafe or not.
Whats a hydraulic device?
Its a device that uses liquid to put pressure from 1 end to the other. You can also multiply force.
What is Pascal's Law
Force plus confined fluids = pressure to all parts of a fluid thats equally distributed
