Explanation of the properties of matter. Hope Its Helpful

1. Properties of Matter
Section 2: Physical Properties

2. Objective
In this lesson you will learn
• Identify six examples of physical properties of
matter
• Describe how density is used to identify
substances

3. Properties of Matter
Review: Matter
• Anything that takes up space contains matter
• Anything that has mass is made up of matter
▫ Books, pens, tables, pencils etc
• Not all Matter looks the same (different color,
texture, size, odor)
• We can tell Matter apart by using our sense of
smell, sight, hearing, touch, taste

5. Physical Properties
• Whenever you want to know about an objects
size, color, odor, mass, and volume you are
talking about its physical properties
• Physical properties relate to how an object looks,
how much it weighs, how it smells, how much
space its taking
• Ex; a car can be:
▫ Red
▫ Weigh 5000kg
▫ Height of 1.5m and length 3m

6. Physical Properties
• The matter in an object can be observed
without changing the matter
▫ Ex; if you want to know how much an apples
weighs, you can just put it on the scale
▫ You don’t have to cook the apple or melt it or
break it down to get this answer
• Physical Property of matter can be observed or
measured without changing the matter’s identity

7. Physical Properties

8. Physical Properties
• We are able to
understand the
physical properties of
matter USING OUR 5
SENSES
• Our senses allow us to
distinguish one thing
from another

9. Physical Properties
Sugar Sand

10. Physical Properties
Sugar Sand
• Color: white
• Odor: no smell
• Touch: rough and grainy
• Color: tan/brown
• Odor: no smell
• Touch: rough and grainy
Other Physical Properties include:
• its state of matter at room temperature (is it a liquid,
solid, or gas)
• Whether or not its magnetic
• Whether or not it floats or sinks in water
• Whether it dissolves in water

11. Physical Properties
• What is the state of sugar and sand at room
temperature?
Solid
• Are either of them magnetic?
No
• Do they floats or sinks in water?
Sink
• Do either of them dissolves in water (solubility)?
Sugar dissolves, but sand does not

12. Physical Properties

13. Physical Properties
• There are several types of physical properties
• The 6 main physical properties are:
▫ Thermal Conductivity
▫ Solubility
▫ Ductility
▫ Malleability
▫ Density
▫ State

14. Examples of Physical Properties
Thermal Conductibility:
• The rate (speed) that an object
transfers heat
Solubility:
• the ability of a substance to
dissolve in another substance

15. Examples of Physical Properties
Ductility
• The ability of a substance to be
pulled into a wire
Malleability
• The ability of a substance to be
rolled or pounded into thin
sheets

16. Examples of Physical Properties
State
• Is the physical form in which a
substance exists, solid liquid
or gas
Density
• Is the mass per unit volume of
a substance. Lead is very dense
so it makes a good sinker for
fishing lines

17. Ductility Malleability

18. Thermal Conductivity

19. Solubility

20. State

21. Physical Properties
Density
• A physical property that
describes the relationship
between mass and volume
• Density is the amount of
matter in a given space
• Ex:
▫ a golf ball and tennis ball
have similar shape
▫ But a golf ball has more mass
than a tennis ball
▫ Therefore the golf ball has a
greater density

22. The 6 Physical Properties
• Thermal Conductivity
• State
• Solubility
• Ductility
• Malleability
• Density

23. Density
• Which would you rather carry a
kilogram of lead or a kilogram
of feathers?
• One piece of lead can weigh a
kilogram, but it would take
many feathers to make a
kilogram
• Therefore lead would be less
awkward to carry

24. Density
• When you know the density of
a substance you would know if
it will float or sink in water
• Can you explain how?
• If the density of an object is less
than the density of water, the
object will float
• If its higher than water then the
object will sink
• The density of water is 1g/cm3

25. Density
• The density of an object is found by dividing
mass by volume:
▫ D=M/V
• D is the density, M is the mass, and V is the
volume
• You divide the mass by the volume to find the
density of an object
• Ex: if an object has a mass of 200g and a volume
of 10cm3 what will the density be?
20 g/cm3

26. More Density Questions
Solve the density for the following
• Mass of 25g and volume of 5cm3
5 g/cm3
• Mass of 900kg and volume of 30L
30 kg/L
• Mass of 40g and volume of 5ml
8 g/ml

27. More Calculations
• What is the volume of an object with a density of
6g/ml and a mass of 300g?
• What is the mass of an object with a density of
8g/cm3 and a volume of 119cm3?
• What is the mass of an object with a density of
2kg/L and a volume of 222L

28. Density-Liquid Layers

29. Density-Liquid Layers
• Each liquid has a different
density
• If you carefully pour each layer
into the cylinder they will form
different layers
• The densest layer (the one
with higher density) will move
to the bottom
• The least dense layer (the one
with lower density) will move
to the top
• Blue is the least dense and
light yellow is the most dense

30. Physical Change
• When a popsicle melts or a soda can is crushed,
the object changes form
• If you take a piece of silver, heated and pounded
into a heart shaped pendant you have changed
the physical shape of the object
• But the piece of silver is still silver
• The properties that make it silver are still the
same

31. Physical Change

33. Physical Change
• When an object goes through a physical change
the matter in the object is the same
• Ex: you can melt a butter and pour it over
popcorn. The shape of the butter has changed,
but the butter is still butter.
• Therefore physical change does NOT effect the
matter inside an object
