Total questions: 20
Worksheet time: 11mins
What are 2 properties of materials?
Density and hardness
Color and taste
Sound and texture
Weight and volume
Explain these 2 properties.
Density relates to weight, and hardness relates to sound.
Density is mass per unit volume, and hardness is resistance to deformation or scratching.
Hardness relates to weight, and density relates to texture.
Both are measures of how a material tastes.
How can you calculate the density of a material?
Divide its mass by its volume.
Multiply its weight by its height.
Divide its weight by its area.
Multiply its mass by its temperature.
What substance is used as a density comparison?
Water
Gold
Steel
Mercury
Give 2 substances that can make a material magnetic.
Copper and aluminum
Iron and nickel
Gold and silver
Zinc and tin
Are all steels magnetic?
Yes, all steels are magnetic.
No, only some steels are magnetic.
Only stainless steels are magnetic.
Steel is not a magnetic material.
What is a type of material strength?
Compressive strength
Magnetic strength
Bend strength
Pressure strength
How do you calculate the UTS of a material?
Divide the maximum load by the original cross-sectional area.
Multiply the material's length by its width.
Divide the material's volume by its weight.
Multiply the material's mass by its height.
How can you test for the UTS of a material?
By a drop test
By a magnetic test
By a tensile test
By an electrical test
What is compressive strength important in?
In determining a material's weight
In determining a material's colour
In determining a material's resistance to being compressed
In determining a material's form
What types of energy can materials conduct?
Sound and light
Heat and electricity
Light and warmth
Weight and sound
What is wear resistance?
The ability of a material to resist degradation
The ability of a material to conduct heat
The ability of a material to produce sound
The ability of a material to change shape
What can be a problem with very tough materials?
They can weigh alot
They can be fragile
They can be hard to shape and cut
They can be easily shaped
What is an extremely hard material?
Cotton
Glass
Diamond
Wood
What is Mohs scale used for?
Measuring density
Measuring weight
Measuring material hardness
Measuring conductivity
What test can you use for hardness?
Tensile test
Brinell test
Compressive test
Sound test
Why is ductility important in materials?
It allows materials to resist bending
It allows materials to conduct electricity.
It allows materials to be shaped without breaking.
It allows materials to resist corrosion
What is material fatigue?
When a material is tired and needs to rest.
The progressive and localized structural damage that occurs when a material is subjected to cyclic loading.
When a material becomes too stretchy.
When a material changes its shaped easily.
Why is material malleability important?
It determines how light a material is.
It determines how a material conduct heat
It allows materials to be hammered or rolled into thin sheets.
It determines the colour of a material.
Why is material density significant?
It determines the material's volume.
It determines the material's colour
It provides insight into the compactness of the material's structure.
It determines the weight per volume of a material.
