properties Flashcards
absorbency
physical- ability to soak in moisture or resistance to moisture. high absorbency = soak in moisture
density
physical- mass per unit volume
fusibility
physical- ability of a material to be converted from a solid into a fluid state and combined with another material
electrical and thermal conductivity.
physical- conduct electricity or transfer heat
what is a physical property
any property measured in natural state
what is a working property
describe how a material responds when manipulated / worked upon
strength
working - ability to withstand forces
tensile strength
compressional strength
hardness
working - ability to withstand impact, wear and abrasion and indentation. may be brittle.
toughness
working- ability to absorb shock and impact without breaking
malleability
working- bent and shaped without cracking
ductility
working - drawn out or stretched without breaking
elasticity
working- return to original shape after being stretched or compressed.
