Transcript Physical and Chemical Changes and Properties Powerpoint -- Presented 08/20 or 08/21




These changes in matter do not result in a
substance with a new _______. In other words
the ________ of the substance remains the
same before and after the change
Examples: MELT BOIL FREEZE CONDENSE
SUBLIME DEPOSIT EVAPORATE CUT MIX
FILTER GRIND DISSOLVE STIR DECANT
CENTRIFUGE
These changes do not involve bond ________
and bond __________.



These changes in matter result in a substance
with a new _________. In other words the
_________ of the substance is altered due to
the change.
Examples: REACT ROT SPOIL DECAY RUST
OXIDIZE REDUCE CORRODE BURN EXPLODE
COOK CHARGE RECHARGE DECOMPOSE
DIGEST RESPIRATION COMBUSTION
PHOTOSYNTHESIS FERMENT
These changes do involve bond _________ and
bond _________.



These properties of matter are observable
without any accompanying _________ in
identity. You need not ________ the identity
of the substance to observe these properties.
Examples: COLOR MASS VOLUME LENGTH
MAGNETISM TEMPERATURE HARDNESS
LUSTER MALLEABILITY CONDUCTIVITY AREA
WEIGHT TEXTURE DENSITY MELTING PT
BOILING PT DIAMETER RADIUS HEIGHT
SOLUBILITY
___________ vs. ___________ Physical Properties



These properties of matter are observable
only with an accompanying ________ in
identity of the substance. You must ________
the identity of the substance to observe these
properties.
Examples: CORROSIVE FLAMMABLE
REACTIVE EXPLOSIVE TOXIC OXIDIZER
REDUCER POISONOUS CAUSTIC
COMBUSTIBLE
Because these properties require a change in
identity, they are usually just _________ forms
of the chemical changes already mentioned.


1) There is no change in molecular/atomic
identity.
2) These changes are generally easily
reversible.







1) Formation of a ___________.
2) Appearance of a new ___________.
3) Energy _______________.
4) Energy _______________.
5) After mixing together two _______________, a
________ _______________ forms.
There is a change in molecular/atomic identity.
Generally speaking chemical changes are not
easily ____________________.
