Properties of materials

Question 1

strength =

Answer 1

ability to withstand forces without breaking. (rope resists pulling forces)

Question 2

Hardness =

Answer 2

ability to withstand scratching/abrasion/denting (tools)

Question 3

toughness =

Answer 3

ability to withstand breaking/snapping (bend instead > armour/bulletproof vest)

Question 4

elasticity =

Answer 4

ability to stretch/bend and return to original shape (spring)

Question 5

malleability =

Answer 5

able to be bent and shaped(most metals -hammered)

Question 6

ductility =

Answer 6

ability to be drawn into a wire

Question 7

electrical conductivity =

Answer 7

how well electricity passes through (conductors-wires-= let pass, insulators-wire coating-= don’t)

Question 8

thermal conductivity =

Answer 8

how well heat passes through something (conductor= pan, insulator=handle)

Question 9

Fusibility =

Answer 9

how well something can be melted and fused together(solder = ^fusibility as it melts before metals being fused together)

Question 10

density =

Answer 10

how much mass something has (solid wood table has a lot of mass =more dense)

Question 11

absorbency =

Answer 11

how well a material can soak up moisture (natural fibres are absorbent- synthetic aren’t)
