1

SC1a - What are the arrangements of particles in each of the three states?

  • Solid: Regular and close together
  • Liquid: Random and close together
  • Gas: Random and far apart

2

SC1a - What are the movements of particles in each of the three states?

  • Solid: Vibrate around a fixed position
  • Liquid: Move around each other
  • Gas: Fast in all directions

3

SC1a - What are the names of the two state changes between solid and liquid?

  • S→ L is Melting
  • L → S is Freezing

4

SC1a - What are the names of the two state changes between liquid and gas?

  • L→ G Evaporating (and Boiling)
  • G → L Condensing

5

SC1a - What are the names of the two state changes between Gas and Solid?

  • G → S Deposition
  • S → G Sublimation
  • During these processes they do not become liquid

6

SC1a - What is overcome during melting and boiling?

Forces of attraction between particles

7

SC1a - In a heating curve, at which points will the line be flat?

During Melting and Boiling [phase changes] as the temperature doesn't increase while the forces of attraction are overcome.
