Material Properties

Question 1

properties referring to the sound transparency i.e. ability of a material to let the radio waves pass, absorb them or reflect them

Answer 1

acoustical properties

Question 2

property of a metal to combine with another material for instance a metal in order to get a blended materi- al

• ->alloyed
  ex. : Copper shows excellent alloying properties

Answer 2

alloying property

Question 3

property of a material, which does not bend under strain and breaks easily when a mechanical shock is ap- plied for example. It is the degree at which a material breaks when a mechanical force is applied on to (e.g. tensile forces, bending forces, compressive forces, shear forces, torsion forces)
–> brittle/fragile

Answer 3

brittleness

Question 4

Definition 1
a substance that enables a chemical reaction to proceed at a usually faster rate or under different conditi- ons (as at a lower temperature) than otherwise possible
Definition 2(none)

Answer 4

catalyst

Question 5

Properties referring to the ability of a material to withstand chemical attacks (exposure to corrosive sub- stances e.g. acids, alkalis) or to react when exposed to certain conditions or to other materials

Answer 5

chemical properties

Question 6

Definition 1
ability of a material to burn
ex.: Unlike stone, gasoline is combustible as well as wood

Definition 2
property of a material that can easily catch fire und burn –> combustibility

Answer 6

combustible

Question 7

electrical conductivity
–> electrically conductive

thermal conductivity
–> thermally conductive

Answer 7

conductivity

Question 8

property of a material to deform when a mechanical force (e.g. compressive force, tensile foce, shear force) is applied to it…before it breaks.
–> ductile

Answer 8

ductility

Question 9

property of a material which can strech under strain but recovers its original shape as soon as the tensile force applied to it is released
–>elastic

Answer 9

elasticity

Question 10

Ability of items or material to either allow the passage of electrons or resist the electrical current (‘resistivity’).

Answer 10

electrical properties

Question 11

adj describing the property of a material which is resistant to damage from fire

Answer 11

fireproof

Question 12

property of a material which…. –>flexible

Answer 12

flexibility

Question 13

property of a material which can resiste the impact of another material –>hard

Answer 13

hardness

Question 14

property of a material which swells as a result of heat exposure, thus increasing in volume and decreasing in density. Intumescents are typically used in passive fire protection

Answer 14

intumescence

Question 15

property of a material to be shapped

Answer 15

malleability

Question 16

Properties of a material or an item to withstand forces (tensiles forces, compressive forces, torsion forces, shear forces, flexion bending forces, bending forces…)
e.g. resilience, elasticity, plasticity, toughness, brittleness

Answer 16

mechanical properties

Question 17

ability of a material to pass, modify or reflect light (optical waves) or changes depending on the waves

Answer 17

optical properties

Question 18

Properties referring to its density surface texture of a material and its size (length, width, depth, height, dia- meter, radius, and circumference)

Answer 18

Physical properties of a material

Question 19

property of a material which can deform under strain whereby undergoes a permanent change in shape and size when the strain exceed a certan value (yield value)
–> plastic

Answer 19

plasticity

Question 20

material has many small voids (holes) so water or air gets through it. –> porosity

Answer 20

porosity

Question 21

refers to the property of a material that can recover its original shape or/and is not destroyed when different types of force are applied to it and afterward released. It is is a property of a ma- terial which can deform in follow of a central force and recovers its original shape (i.e. possibly bouncing back).

Answer 21

resilience or resiliency

Question 22

….

Answer 22

semiconductivity

Question 23

property of a material which doesn’t show much resistance to the impact of another material (i.e. can be bent easily, can deform and cannot withstand mechanical shocks for instance)
–> soft

Answer 23

softness

Question 24

property of a material which

–>stiff

Answer 24

stiffness

Question 25

Properties referring either to the ability of material to conduct heat or insulate from ambient temperatures

Answer 25

Thermal properties

Question 26

–> tough

Answer 26

toughness

Question 27

material, that can let pass light partially but the material is not transparent, e.g. wax or sheets

Answer 27

translucency

Question 28

property of a material which can let visible images passes through –>transparent

Answer 28

transparency
