Fluids
material that has no fixed shape and is free to flow
What is a fluid?
This refers to the thickness or thinness of a liquid
What is viscosity?
This is the equation for finding density
What is mass divided by volume?
The ability to float in water or air or some other fluid
What is buoyancy?
Kneeling buses are an example of this pressure being used in daily life.
What is pneumatic pressure?
This fluid is used to transport and take materials to cells in the human body
What is blood?
Ketchup, molasses, corn syrup, and honey are all examples of liquids that have this
What is high viscosity?
To find the volume of an irregular object, one can find volume using this?
What is displacement?
This state of matter is the most compressible
What is a gas?
Objects made of the same material always have the same density (T or F)
True
This is a smooth pattern of flow and is ideal for aerodynamics because it reduces drag.
What is laminar flow?
Water and vegetable oil are examples of liquids that have this
What is low viscosity?
On the moon, this would remain the same.
What is mass?
This state of matter is the least compressible
What is a solid?
When water freezes, it becomes more dense (T or F)
False (less dense)
This is an irregular, mixing flow pattern
What is turbulent flow?
This is the force of attraction between the particles of one substane and the particles of another substance.
What is adhesion?
This is the measurement of the force of gravity pulling on an object
What is weight?
This law states that a force applied to a fluid is distributed equally through all parts of the fluid
What is Pascal's Law?
Thermometers use this principle to provide accurate temperature readings.
What is thermal expansion?
This fluid eliminates dissolved waste from the body
What is urine?
This is the measure of how stongly the particles of a fluid attract each other. Surface tension is an example of this.
What is cohesion?
This is the measure of the amount of matter in a given volume of a substance
What is density?
Aside from buoyancy, this other force acts on an object in a fluid, and is opposite that of the buoyancy force.
What is gravity?
Liquids have a definite shape and a definite volume (T or F)
False (Liquids do not have a definite shape)
