問題一覧

materials that relate to its behavior in chemical reactions

chemical property

process of metal destruction when interacts to is environment fur to the conversion of metal compounds into oxide and sulfide

corrosion

it show the physical behavior of the material

physical properties

process of producing a new material by combining 2 or more melted elements

alloying

describe the response of materials to electrical loads

electrical properties

electrical property depends on the geometry of the material (extrinsic)

Resistance

independent with its geometry(instristic) and property that resist the flow of current

resistivity

recoprocal of resistivity

conductivity

material cane be insulator or semi-conductor if the valence band is completely filled at 0 K.

electrical properties

concerned w/ the response of material to electromagnetic radiation

optical properties

described how much light is radiated (emitted) from the material in relation to an amount which radiates black body at same temp

emissivity

wavelength relationships of photon

energy

how much light absorbed in material relation to an amount of light incident on the material

absorptivity

range of colors produced w/ the reaction pf material electrin and the photons of absorb wavelengths

absorption spectrum

transmit small to no visible light

opaque

how much light transmitted through material

transmissity

transmit some light

transculent

transmit almost of light

transparent

amount of light incident on material

reflectivity

the light reflect at the same angle as it hit the surface

spectacular reflection

light hit on object and reflect in lots of different directions

diffuse reflection

bending the light as it passes through a materiak and reduces its speed

refraction

ratio of the sines of the angle of incident and refraction is equivalent to the ratio of phase velocities in 2 media

snell’s law
