If a substance flows slowly it is ___
Viscous
100
You have a gem with a volume of 15cm^3 and a mass of 45g. What is its density?
You divide mass by volume:
-> 45/15 = 3g/cm^3
100
A fluids upward force on an object submerged in the fluid is known as?
Archimedes' Principle
100
What are the three types of buoyancy?
Negative, Positive, and Neutral
100
The explanation of why fluids act the way they do
What is the particle theory/particle theory of matter?
200
what is viscosity?
Viscosity is a measure of a fluid's resistance to flow and it describes the internal friction of a moving fluid.
200
How does one determine the volume of a substance using water?
One would utilize the displacement method to determine the volume of the substance, as water which is displaced is equal to the substance's volume. In order to discover the volume of the substance one would subtract the original volume of the water from the volume of the substance submerged in water.
200
The man who discovered the concept of displacement and buoyancy was?
Archimedes.
200
What do fluids include?
Fluids include liquids, gasses, and plasmas
200
Name two ways fluids help our bodies
-> Move nutrients and waste through our bodies
-> Protect our joints and organs
300
Which one of these fluids has a higher viscosity; ranch, or mustard?
Mustard has a higher viscosity
300
What is density?
The amount of mass in a given space.
300
How do bony fish change their buoyancy in water?
Bony fish use their swim bladder to change their buoyancy in water. They do this by altering the amount of oxygen in the bladder which causes them to rise or sink.
300
Why do fluids flow?
Because the particles of liquids and gases are free to move about.
300
What are characteristics of fluids?
-> They don't have a fixed shape
-> They take shape of the containers they're put in
400
What factors affect the viscosity or a fluids ability to flow?
Cohesion and adhesion
400
Put the liquids from most dense to least dense
Honey, corn syrup, dish soap, water (with food coloring), and vegetable oil
400
Why does an unpeeled orange float but a peeled orange sinks?
The rind of an orange is porous and contains pockets of air. This makes it less dense when it is unpeeled.
400
What is more viscous, corn syrup, water, or oil?
corn syrup is the most viscous
400
Fluids that flow slowly have a high what?
Viscosity.
500
Which of the following statements is true?:
A - Milk has a surface tension with your lips and creates a cohesive "skin"
B - Maple syrup is a solid because it is very viscous
C - Fluids with less cohesion would have higher flow
D - When heat is applied to sugar it makes it very viscous
D - When heat is applied to sugar it makes it very viscous. When you apply heat to sugar, it thickens up which creates caramel. As you may know, caramel is so viscous you can fold it on top of itself.
500
How do you find density?
Divide mass by volume
500
Which of the following is the application of buoyant force?
-> Hot air balloons
-> Fishes
-> Submarines
-> All of the above
All of the above
500
What is the difference between liquids and fluids?
Fluids can low and they have some viscosity. Liquids also flow and have volume, although they don't have a definite shape.
500
Most fluids have a freezing point. At this temperature it becomes ___
Solid
