Properties of materials

Question 1

define working properties

Answer 1

materials which respond to use in a certain environment or in a certain way- e .g- something with become hot when heated

Question 2

define material properties

Answer 2

characteristics of a material, what it’s good at doing

Question 3

define physical properties

Answer 3

a property which is an inherent property of a material, it is what it is naturally, e .g- a metal can naturally conduct electricity

Question 4

Examples of physical properties

Answer 4

• absorbency
  -fusibility
  -density

Question 5

What is absorbency? + Examples

Answer 5

the tendency to attract or take an element, usually a liquid such as water, e.g.- sponge

Question 6

What is density?+ examples

Answer 6

how compact a material is; the mass per unit of volume of a material

Question 7

What is fusibility? +Examples

Answer 7

the ability of a material to be converted from a solid to liquid using heat
- solder has a high fusibility

Question 8

What is strength?

Answer 8

• the ability of a material to withstand force without breaking

Question 9

What is elasticity

Answer 9

• the ability of a material to stretch and bend and then be able to return to its normal shape

Question 10

what is toughness

Answer 10

• the ability of a material to absorb energy through shock without breaking

e.g. wood

Question 11

what is malleability

Answer 11

the ability of a material to be shaped without breaking

Question 12

what is ductility

Answer 12

the ability of a material to be drawn into wires without breaking

Question 13

what is hardness

Answer 13

the ability of a material to resist scratches and indentations, it doesn’t dent

Question 14

other properties of absorbent materials

Answer 14

• can be dyed easily
• dry slower
• vulnerable to stains
