| diffusion | when moving particles spread out and mix together.
🗑

| changing from one state to another | energy is needed
🗑
|
||||
| melting point | the temperature at which particles MOVE away from their FIXED position
🗑
|
||||
| boiling point | the temperature at which particles BREAK away from each other completely and turn into bubbles of gas.
🗑
|
||||
| pressure | when gas particles pound against the walls of their container. Higher the temperature the greater the pressure.
🗑

||||
| density |
🗑
