Physical and Chemical Properties Flashcards
(19 cards)
Ductile
capable of being shaped or bent or drawn out into a wire
Malleable
capable of being shaped or bent with a hammer
conductor
a substance that readily transfers energy e.g. electricity and heat
insulator
a substance that does not readily transfer energy e.g. electricity and heat
luster
the visual property of something that shines with reflected light
flammable
able to catch fire easily
reactive
likely to undergo a chemical change
boiling point
temperature at which an object will change from liquid to gas
density
the ratio of mass to volume (density=mass/Volume)
hardness
the scratchability of a substance
brittle
the ability of an object to break when it is struck with a hammer
melting point
temperature at which an object will change from soli to liquid
viscosity
the ability of an liquid to resist flowing (thickness)
distillation
the process of purifying a liquid by boiling it and condensing its vapors
filtering
the process of separating a mixture by the size of its particles
decanting
pouring liquid off the top when sediment has settled to the bottom
centrifugation
the process of separating substances by the use of a centrifuge … used to separate cells or mixtures of cells without destroying them; you spin them and they settle at different levels in the test tube on the basis of their respective densities
chromotography
A process which separates the parts of a solution with special paper and a solvent.
magnetic
a characteristic of those metals that are attracted to magnets and can be made into magnets
