This document defines and provides examples of chemical and physical properties of matter. Chemical properties describe characteristics only observed when a substance changes into another, such as combustibility. Physical properties can be observed without a substance changing, including state, color, odor, and conductivity. The document uses examples like magnesium combustion and metal reactivity to illustrate chemical properties, and discusses physical properties such as luster, brittleness, and solubility. Videos are also included to visually demonstrate different properties.

1. Chemical & Physical
Properties of Matter

2. Chemical Properties
• Characteristics that are
observed ONLY when a
substance changes into a
different substance

3. Chemical Properties
• Types of Chemical Properties:
• Combustible/flammable:
• able to burn
• Examples & Facts:
• all chemicals come with a
label that identifies their level
of flammability

4. Chemical Properties
• Types of Chemical Properties:
• Combustible/flammable:
• able to burn

− 1:30 Combustion of Mg
• Examples & Facts:
• oxygen & hydrogen are very
flammable gases
• carbon dioxide is not a very
flammable gas

• Stop at 35 seconds

6. Chemical Properties
• Types of Chemical Properties:
• Reactivity:
• how easily a substance reacts
with another substance

− 1:10 min Alkali metals reaction to water
• Examples & Facts:
• many chemicals react with
water or oxygen
• all chemicals come with a
label that identifies their level
of reactivity

7. Chemical Properties
• Types of Chemical Properties:
• Reactivity:
• how easily a substance
reacts with another
substance
• Examples & Facts:
• corrosion: slow reaction
& wearing away of metals
(rusting, tarnishing)

8. Examples of Chemical
Changes

9. Physical Properties
• Characteristics that can be
observed without changing the
substance into something else

10. Physical Properties
• Types of Physical Properties:
•
•
•
•
•
•
•
color
texture
odor
taste
hardness
magnetic
boiling, melting, & freezing points

11. Physical Properties
• Types of Physical Properties:
• Luster:
• shininess or dullness
• Examples & Facts:
• most metals are shiny
• diamonds have a lot of
luster
• many minerals are dull

12. Physical Properties
• Types of Physical Properties:
• Brittleness:
• how easily a substance breaks into
pieces
• Examples & Facts:
• very brittle substances
may crumble or break
with very little force

13. Physical Properties
• Types of Physical Properties:
• Brittleness:
• how easily a substance breaks into
pieces
• Examples & Facts:
• many rocks & minerals
are brittle
• chalk is brittle because
it crumbles easily

14. Physical Properties
• Types of Physical Properties:
• Malleable:
• can be pounded into shapes
• Examples & Facts:
• aluminum is very malleable
• clay is also malleable
• substances that are malleable
are usually not very brittle

16. Physical Properties
• Types of Physical Properties:
• Ductile:
• can be pulled out into a long wire
• Examples & Facts:
• substances may be both malleable
& ductile
• copper is very malleable &
ductile
• substances that are ductile
are usually not very brittle

17. Physical Properties
• Types of Physical Properties:
• Conductive:
• can transmit heat and/or electricity
• Examples & Facts:
• a substance may conduct
heat, electricity, neither, or both
• most metals are good
conductors

18. Physical Properties
• Types of Physical Properties:
• Conductive:
• can transmit heat and/or
electricity
• Examples & Facts:
• pots & pans are made out of metals
that are good heat conductors

19. Physical Properties
• Types of Physical Properties:
• Soluble:
• can be dissolved in a liquid
• Examples & Facts:
• substances that are “watersoluble” will dissolve in water
• salt & sugar are soluble in
water
• substances that don’t dissolve
are “insoluble”

21. Models are
representations of
objects or systems.
Models can be used for:
• Understanding something
• Predicting
• Picturing things in your mind
• Explain scientific theories

22. Physical Models
• look like the object they model.

23. Mathematical models
• Made up of mathematical
equations and data

24. Conceptual models
• Systems of ideas.

25. Limitation of Models
• They don’t act exactly like the
things they model or they may
not look like the things they
represent. Scale might be
incorrect.
• What is wrong with this model?
