Transcripts - Kinetic Model of Matter
The Kinetic Model of Matter
MAIN IDEA NO. 1
is made up of tiny particles…
parts of atoms
MAIN IDEA NO. 2
The particles are constantly moving
MAIN IDEA NO. 3
When the temperature goes up,
the particles move faster.
When the temperature goes
down, the particles move slower.
When the temperature is at
absolute zero (-273 Celsius), the
particles stop moving
MAIN IDEA NO. 4
Matter contracts when
molecules do not
move as fast.
Matter expands when heated
because faster moving
molecules move further.
MAIN IDEA NO. 5
Matter exists in 4 states
MAIN IDEA NO. 6
In solids the molecules are
closely packed by the forces
They vibrate constantly
about the fixed positions.
They have definite shape
MAIN IDEA NO. 7
In liquids the molecules are slightly
farther apart than in solids.
Molecules vibrate, at the same
move rapidly over short distances,
slipping past each other in all
Liquids don’t have definite shape
but have definite volume.
MAIN IDEA NO. 8
The molecules in gases are much
farther apart than in solids or
Molecules move randomly at very
high speed in all the space
available. They hit each other and
collide with the wall of the container.
Gases go not have definite shape
MAIN IDEA NO. 9
Temperatures are so high that
atoms come apart. We think the
and the are made of
plasma. On the Earth, plasma is
found in ,
Fluorescent light bulbs
Plasma screen TV’s
metal cutting torches
MAIN IDEA NO. 10
The Brownian movement (movement of
particles in a fluid) is named after Robert Brown
The botanist who first
discovered the continuous,
random motion of pollen
grains, suspended in water,
and deduced that water
molecules were in constant,
1. What is the Absolute Zero in Kelvin degrees?
2. What happens to a solid when it is heated?
3. What is the 4th state of matter?
4. What are the two states of matter that cannot be compressed?
5. What happens to matter when it is cooled?
6. What does not have definite shape but has a definite volume?
7. Who discovered the Brownian motion?
8. How did he he discover it?
9. What state of matter have molecules that are randomly arranged and slightly far
10. What state of matter has the lowest density?
11. What object can exist in all three states of matter?
12. What is the Brownian Motion?
13. What state of matter has the highest temperatures?
14. What is matter made up of?
15. What state of matter has closely packed molecules?
