This document discusses matter and its properties. It defines the three common states of matter as solid, liquid, and gas. Solids have a definite shape and volume, with particles that are close together. Liquids take the shape of their container but have a definite volume, and their particles can move past one another. Gases spread out to fill their container and do not have a definite volume. The document also distinguishes between physical and chemical properties, and physical and chemical changes. Scientists use tools like balances and measuring cups to measure the mass and volume of matter.

Definite Shape.
Definite Volume.
Particles close together, fixed.
Little free space between particles
Does not flow easily

10. The 6 Phase Changes
1.Melting: Solid to Liquid
2.Freezing: Liquid to Solid
3.Evaporation: Liquid to Gas
4.Condensation: Gas to Liquid
5.Sublimation: Solid to Gas
6.Deposition: Gas to Solid

13. Physical properties
Physical properties can be observed or measured
without changing the identity of the matter.
Basically, properties you notice when using one of
your five senses:
Feel - mass, volume, texture
Sight - color
Hear
Smell
Taste
15. Physical properties
The measurement of mass and other
characteristics that can be seen without
changing how that object looks are its physical
properties.
When you look at oranges, you know that they
are oranges because of their color, shape, and
smell.
Mass, color, shape, volume, and density are some
physical properties.
16. Properties of Matter
• A property describes how an object looks,
feels, or acts.
• The objects shown here have different
kinds of properties:
18. Physical Changes
Changes that do NOT change the identity of
the substance.
You may or may not be able to undo a physical
change.
19. Physical Changes: • For example:
• 1. Size 2. Shape
• 3. State
- solid liquid gas
• 4. Dilutions
• The water doesn't turn
into soil or macaroni.
• It remains water.
• If it did change into soil
or macaroni, your drink
would taste terrible and
you would have an example
of a chemical change
20. • If you remember, ice is water in the solid
state.
• When you drop the ice cube into the liquid,
it begins to melt because the temperature is
higher than that of the ice cube.
• It's like putting a snowman on your front
lawn in July.
• The ice cube becomes liquid water.
• This is an example of a physical change.
• The solid water turned to liquid water.
22. Chemical properties
A common chemical property is
reactivity.
Reactive to oxygen
Reactive to air
Reactive to water…
Notice that chemical propertiesNotice that chemical properties
aren’t EASY to observe, unlikearen’t EASY to observe, unlike
physical properties.physical properties.
23. Chemical Changes
Chemical changes do alter the identity of a
substance
In other words, a chemical change is when
something changes into an entirely different
substance
For example:
Iron rusting
Wood burning
Copper turning to brass
Baking a cake
spoiled milk
24. Chemical properties-
• These are properties that
can only be observed by
changing the identity of the
substance.
• A piece of paper burns and
turns to a black substance.
• After the flame goes out
you can no longer burn the
new substance.
• The chemical properties have
been changed.
25. Milk needs to be in the
refrigerator or else it will
go bad.
If you've ever seen or
smelled spoiled milk, it is
not a pretty sight.
The milk gets a sour odor
and becomes lumpy.
Unlike physical changes,
you cannot reverse chemical
changes.
You can melt ice to get
water and freeze that
water to get ice again.
You cannot make milk
unspoiled.
26. Physical vs. Chemical
Physical properties: observe without
changing the identity of the substance
Chemical properties: observe only when
the identity changes
How do you know if it is chemical or
physical?
If it CHanges, it’s CHemical
28. Measuring Matter
Essential ideaEssential idea
““Scientists use tools toScientists use tools to
measure the mass and volumemeasure the mass and volume
of matter”of matter”
29. Mass
• Mass is the amount of
matter in an object. Unit of
mass is the gram (g). You
measure mass using the
balance.
30. Volume
• Volume is the
amount of space
an object takes
up. A unit of
volume is liter (L).
You can use
measuring cup to
measure liquids.
31. Density
• Density is the amount of mass
of a certain volume of an object.
Two object can have the same
volume but different masses.
You have to compare equal
volumes of both kinds of matter
to compare the density of each
object
33. Review Questions
1. What state of matter has definite
volume and definite shape?
2. Describe the properties of liquids.
3. Describe the differences between gas
and liquid.
4. What are physical properties?
