chemistry notes ( chapter 2 )

kinetic particle theory

states that all matter is made up of tiny particle and are in constant motion

solid qualities

1. particle arrangement = very closely packed in a orderly manner

2. particle movement = vibrate and rotate about fixed positions

3. forces of attraction = very strong

4. kinetic energy = very low

5. shape = definite

6. volume = definite

7. cannot be compressed

liquid qualities

1. particle arrangement = closely packed in a disorderly manner

2. particle movement = slide past each other freely

3. forces of attractions = less strong

4. kinetic energy = low

5. shape = indefinite

6. volume = definite

7. cannot be compressed

gas qualities

1. particle arrangement = very far apart in disorderly manner

2. particle movement = move quickly and randomly in any direction

3. forces of attractions = very weak

4. kinetic energy = high

5. shape = indefinite

6. volume = indefinite

7. cannot be compressed

sublimation

the processes by which a solid change directly to a gas

vapour deposition

the process where a gas are cooled until a solid
