1
Q
What is a particle?
A
A tiny bit of matter
2
Q
What does the particle model describe?
A
The movement/arrangement of solids, liquids and gases
3
Q
Describe: SOLIDS
A
- Regular arrangement
- Very closely packed together
- Vibrate at fixed positions
4
Q
Describe: LIQUIDS
A
- Random arrangement
- Relatively close together
- Move around each other
5
Q
Describe: GAS
A
- Random arrangement
- Far apart
- Move quickly in all directions
6
Q
Why can’t you compress solids/liquids?
A
They have little to no space to move to, unlike gases which have lots of free space in between them
