Viscosity
This is what viscosity is.
What is causes fluids to NOT flow easily?
The amount of mass in a given volume.
What is Density?
This is what buoyancy is described as...
What is the upward force that keeps things afloat in liquids.
This is what pressure is.
What is the amount of force applied to a given area?
Substances that flow.
What are fluids?
This causes high viscosity fluids to flow slowly.
what is resistance or internal friction?
This is the formula for density.
What is density = mass divided by volume?
The mathematician from Rome who figured out how to use water displacement to determine the volume of unusually shaped objects.
Who is Archimedes?
This is a decrease in volume caused by force.
What is compression?
The 2 types of fluids.
What are liquids and gases?
This happens to a fluid's viscosity when it is heated up.
What is... it will have a lower viscosity?
A substance with a high density than another substance will ________ and a substance with less density than another will ________.
What is sink and float?
This is what fish have to help them move up and down in the water while swimming.
What is a fish bladder?
This states that an enclosed fluid transmits pressure equally in all directions.
What is Pascal's Law?
What is the particle theory?
When particles have little resistance/friction while flowing.
What is low viscosity?
When _______ is applied, the amount of particles stays the same, but the volume increases which _______ the density?
What is heat and decreases?
This is how a fish bladder works.
What is..... lets in air to go up and lets out air to go down.
Thus system is a closed system that uses liquids under pressure to move things and this other system uses moving air pressure to move things.
What is hydraulic system and pneumatic system?
This determines how far apart or close together the particles are.
What is the forces of attraction?
This determines how fast a fluid flows?
What is flow rate?
A substance has a grater density when in it's ________ state?
What is solid?
This is how very large ships can stay afloat in the water.
What is... the displacement of the water creates a greater buoyant force?
The ___________ is an example of a hydraulic system in the human body and the ___________ is an example of a pneumatic system in the body.
What is heart and lungs?
This is what causes potholes and cracks on roads.
What is thermal expansion?
