Its Matter!
All matter has:
Mass and volume
Do particles in a solid move?
No, they only vibrate
What is it called when a solid becomes a liquid?
Melting
What does compress mean?
To remove space
What kind of shape does a solid have?
A fixed shape, or does not change
Mass is:
How much matter something has, or weight
The particles of a liquid move:
Within the liquid
What is it called when a liquid becomes a gas?
Evaporation
What does expand mean?
To increase space
What shape does a liquid have?
It takes the shape of the container
Volume is:
How much space something takes up
How do the particles of a gas move?
They move freely
What do I have to do to make a liquid become a solid? (freeze)
Remove energy
Why can I compress gases easily?
Because there is space between particles to remove
What shape and volume do gases have?
Gases take the shape and volume of the container
Is heat matter? Explain
No, heat does not have mass or volume
What is in between gas particles?
Empty space
What do I have to do to make a liquid become a gas (evaporate)?
Add energy
Double Points:
Why is it hard to compress solids?
The particles are tightly packed, so it is hard to remove even more space
What happens when we continually add gases into a container?
The space compresses and the particles squeeze together
Is air considered matter? Why
Air is matter because it has both mass and volume
How does an odor get from one place to another?
The odor particles mix with air and then move from place to place
Double Points!
What is it called when a gas becomes a liquid? How do I make it happen?
it is called condensation, we remove energy
Which state of matter has the most space between particles?
Gas
As energy is increased, what happens to particle movement?
The particles move faster
