PROPERTIES of MATTER

PHYSICAL SCIENCE


Physical vs chemical
PHYSICAL vs. CHEMICAL

  • PHYSICAL =

    THE OUTSIDE OF AN OBJECT – USING YOUR 5 SENSES

  • CHEMICAL =

    INSIDE AN OBJECT – WHAT MAKES IT THAT SUBSTANCE.


Physical properties
PHYSICAL PROPERTIES

  • ANY CHARACTERISTIC THAT DESCRIBES THE EXTERIOR QUALITIES OF AN OBJECT USING YOUR FIVE SENSES.

  • VISCOSITY

  • TEXTURE

  • LUSTER

  • TEMPERATURE

  • STATE OF MATTER

  • DUCTILITY

  • ELASTICITY

  • MALLEABILITY

  • CONDUCTIVITY

  • ABSORBENCY

  • BRITTLENESS

  • MASS

  • VOLUME

  • COLOR

  • HARDNESS

  • MAGNETISM

  • WEIGHT

  • DENSITY

  • MELTING/BOILING/FREEZING POINT

  • DISSOLVABILITY


Chemical properties
CHEMICAL PROPERTIES

  • ANY CHARACTERISTIC THAT DESCRIBES THE INTERNAL QUALITIES THAT MAKE SOMETHING WHAT IT IS & IT’S ABILITY TO CHANGE.

  • FLAMMABILITY

  • REACTIVITY TO:

    • Light

  • OXIDATION (RUST)

  • TENDENCY TO FORM COMPOUNDS

  • CHEMICAL STABILITY

  • PH LEVEL / ACIDITY

Physical changes
PHYSICAL CHANGES

  • ANY CHANGE TO AN OBJECT THAT DOES NOT CHANGE THE ORIGINAL ATOMS THAT MAKE IT UP – NO CHANGE IN MATTER

  • SHAPE

  • FORM

  • SIZE

  • STATE OF MATTER

  • BENDING

  • CUTTING

  • MELTING

  • FREEZING


Chemical changes
CHEMICAL CHANGES

  • ANY CHANGE WHICH CAUSES ONE TYPE OF MATTER TO CHANGE TO ANOTHER WITH DIFFERENT PROPERTIES (CAUSED BY A CHEMICAL REACTION)

  • ARE sometimes IRREVERSIBLE

  • BURNING AN OBJECT

  • CHEMICAL REACTIONS

  • RUSTING

  • FORMING A COMPOUNDS

  • DECOMPOSING MATTER

  • PERMING HAIR

  • SONG


Mixtures
MIXTURES

  • CREATING A MIXTURE IS A PHYSICAL CHANGE. YOU STILL HAVE THE ORIGINAL SUBSTANCES YOU BEGAN WITH, BUT THEY JUST SHARE SPACE!

  • EXAMPLES:

    • KOOL AID

    • PIZZA

    • TRAIL MIX

    • SALAD

    • SWEET TEA

    • SODA

DO ALL THESE THINGS LOOK THE SAME TO YOU?


Types of mixtures
TYPES OF MIXTURES

THESE ARE CALLED SOLUTIONS!

  • HOMOGENOUS – (same) MIXTURES THAT LOOK THE SAME ALL THE WAY THROUGH – CANT SEE THE DIFFERENT TYPES OF MATTER

  • EXAMPLES:

    • KOOL AID, SWEET TEA & SODA

  • SOLVENT – WHAT DOES THE DISSOLVING (usually a liquid)

  • SOLUTE – WHAT DISSOLVES (solid)


Types of mixtures1
TYPES OF MIXTURES

THESE ARE EASY TO SEE & SEPARATE!

  • HETEROGENOUS - MIXTURES THAT YOU CAN SEE THE DIFFERENT TYPES OF MATTER ITS MADE OF.

  • BIGGER PIECES

  • EXAMPLES:

    • SALAD

    • PIZZA

    • TRAIL MIX
