Properties of Solids
100
Define “density”
Density describes how much matter (“stuff”) is packed into a specific volume of material.
100
Define “volume.”
Volume is the amount of space that a material fills up.
100
Define “buoyancy.”
Buoyancy is a measure of the upward force on an object in a fluid.
100
What is a synonym for pressure?
A push.
100
Strength describes:
the power to resist strain or stress
200
Which is denser, metal or wood?
Metal.
200
What is the unit used to measure volume depends on what?
Whether the object is a solid or liquid.
200
An object with an average density greater than the density of water will:
Sink.
200
Describe the direction of pressure in a fluid.
Equally in all directions
200
Elasticity describes:
The ability of a material to be stretched and return to its original shape
300
Solids that are strong are usually:
More dense than solids that are not strong
300
The unit used to measure the volume of solids is:
The centimeter
300
An object with an average density less than the density of water will:
Float.
300
Bernoulli’s principle says that:
as the speed of a moving fluid increases, the pressure within the fluid decreases.
300
Brittleness describes:
How quickly a material will break when subjected to pressure
400
Water is an exception to the density rule, because:
The density of solid water (ice) is less than the density of liquid water.
400
The unit used to measure the volume of liquids is?
The volume of liquids is measured in milliliters.
400
To make a heavy material like steel float, you have to:
expand its surface area
400
One of the most important applications of Bernoulli’s principle is:
in the flight of airplanes
400
What is ductility?
The ability to be shaped or molded.
500
The formula for density is:
D = m/v
500
What is the method for finding the volume of an irregular object?
Displacement
500
Archimedes’ principle states that:
the buoyant force on an object is equal to the weight of the fluid it displaces.
500
Streamlines are imaginary lines drawn to:
show the path of the flow of a fluid
500
A material is crystalline if:
its molecules have a regular repeating pattern.
