Slide Content

Physical vs. Chemical Properties

Physical Property
•Any property that can
be observed without
changing the
composition of the
substance

5 Senses
•Sight
•Smell
•Taste
•Touch
•Hearing

Viscosity
•Tendency of a fluid to
keep from flowing
•The greater the
viscosity, the slower the
liquid moves

Conductivity
•Material’s ability to
allow heat or electricity
to flow

Malleability
•Ability of a material to
be shaped or
hammered without
breaking

Hardness
•Ability of a material to
be scratched

Melting & Boiling Points
•Each substance has
their own
•Can be used to identify
a substance

Density
•Mass/volume
•Can be used to test the
purity of a substance

Chemical Properties
•Ability to produce a
change in the
composition of matter
•Can be observed only as
the matter is changing

Flammability
•Material’s ability to
burn in the presence of
oxygen

Reactivity
•How readily a substance
combines chemically
with other substances

•What are some differences between chemical
& physical properties?

•What properties (physical or chemical) are
helpful in identifying a substance?
