1. INTRODUCTION TO MATTER

2. CONCEPTS EXPLORED IN THIS LESSON
1) Matter
Matter, mass, volume, mass vs. weight
2) States of Matter
3 states of matter: solid, liquid and gas
3) Changes of State
Processes that change states of matter
melting
freezing
condensation
evaporation
sublimation
deposition
Temperatures at which changes of state happen
melting point
freezing point
condensing point
boiling point
4) The Particle Theory of Matter

3. MATTER Matter: Is anything that has _____ and _______. mass volume
Is the measure of the ________ of matter
quantity
(the amount of _____ )
atoms
a substance contains.
Units used:
g (grams)
kg (kilograms)
Note: There is usually confusion between the term mass and weight….let’s clarify...

4. BUT the mass (amount of atoms) will remain the same.
MATTER
Mass
Weight
Mass depends on the _______________ in an object.
Weight depends on the _______________
number of atoms
amount of gravity
acting on the amount of ____ contained in an object.
mass
weight = 5000 kg
weight = 833 kg
Since the Moon is 1/6th the size of Earth, it has 1/6th of Earth’s gravitational pull.
mass = 5000 kg
mass = 5000 kg
This means that objects will weigh 1/6th LESS on the Moon than on Earth.
Earth
BUT the mass (amount of atoms) will remain the same.
Moon

5. MATTER Matter: Is anything that has _____ and _______. mass volume
Is the measure of the ________ of matter
quantity
(the amount of _____ )
atoms
a substance contains.
Units used:
g (grams)
kg (kilograms)
Volume:
Is the measure of the _______________ a substance takes up.
amount of space
Units used:
mL (milliliters)
L (liters)

6. STATES OF MATTER Matter comes in 3 States: Solid Liquid 3 States Gas
Guess these states of matter.
Matter comes in 3 States:
Solid
Liquid
3 States
Gas

7. STATES OF MATTER Distance Between Particles & Energy of Particles
definite = unchangeable
indefinite = changeable
Distance Between Particles
& Energy of Particles
Shape
Volume
definite
definite
small distances
Solid
low energy and
little movement
(vibrations only)
indefinite
definite
more distance
Liquid
more energy
and more
movement
Takes the shape of any container.
indefinite
indefinite
large distances
Fills the entire volume of any size of container.
Gas
high energy
and a lot of
movement
Takes the shape of any container.

8. CHANGES OF STATE Matter can change from one state to another through
six different change of state _________.
processes

matter in the diagram.
Next to each arrow,
name the process that
causes the change of
state.
sublimation
condensation
gas
deposition
evaporation
melting
freezing
liquid
solid
