properties of materials: physical Flashcards
physical
what is absorbency
and examples
ability to soak up moisture, light or heat like paper or cotton unlike man-made materials like polystyrene
physical
what is density
and examples
how solid an material is, mass/volume like lead
physical
what is fusibility
and examples
how able a materail can be heated and joiuned to another material when cooled like wbbing is fusible and can be ironed onto fabrics
physical
what is themal and electrical conductivity
and examples
ability to conduct heat (like steel) and electrical current easily passing through a material (like water and copper)
physical
what is electrical restistance and magnetism
and examples
when materials oppose flow of current like resistors
iron, nickel, cobalt
physical
what is chemical heat of combustion
and examples
combustion is burning like bleach
physical
what is chemical toxicity
and examples
how much a subsatnce can damage an animal, cell, organ or plant like an acid
physical
what is chemical oxidation state
and examples
ability when material reacts with oxygen like rust with iron
working
what are the different types of strength and the forces
tensile, stretching/pulling force
compression, pushing/crushing force
shear, sliding/cutting force
torsional, twisting force
working
what is hardness
withstanding impact and abrasive wear with no damage
working
what is toughness
withstanding sudden imapct can absorb shock
working
what is ductility
materials that can be stretched like cooper into wires
working
what is malleability
able to bend or shaped easily, deform under pressure like gold and silver
working
what is elasticity
ablitiy to be streched then returned back into shape
working
what is durability
withstanding wear and tear
