Unit 302 Outcome 2 Materials Properties Quiz

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
