Properties of Materials

Strength is the ability to withstand forces without ________.

• breaking

• bending

• melting

• shrinking

Which property is the ability to withstand scratching, abrasion or denting? E.g. High-carbon steel used to make tools/drill bits etc.

• Strength

• Hardness

• Toughness

• Elasticity

If a material is tough, it is hard to _______ or snap—the material changes shape a bit instead.

• break

• bend

• melt

• stretch

Elastic materials can stretch and return to their original shape. E.g. _______ has good elasticity.

• a spring

• a wire

• bonded fabric

• woven fabric

Materials that are malleable can be bent and _______. E.g. Metal can be hammered into thin sheets without breaking.

• shaped

• drawn into a wire

• dissolved

• melted

Ductile materials can be drawn into a _______. E.g. Copper.

• wire

• sheet

• rod

• block

Electrical conductors let electricity travel through them easily e.g. metals. Electrical _______, like plastic don't.

• insulators

• metals

• wires

• generators

Thermal conductors let heat travel through them easily e.g. metals. Thermal _______ , like wood and plastic don't.

• insulators

• conductors

• metals

• liquids

Materials with a high fusibility have _______ melting points. So that only a small amount of heating is required to convert these materials to liquids. E.g. solder has a higher fusibility than the metals that are being soldered together with it.

• low

• high

• moderate

• variable

The density of a material is a measure of its mass per unit _______.

• volume

• length

• area

• height
