Answer 1

• Regular
• Vibrating about fixed positions

Question 2

Answer 2

• Random, close together
• Move around each other

Question 3

Gas - Arrangement of particles + movement of particles

Answer 3

• Far apart, random
• Fast in all directions

Question 4

Solid to liquid

Answer 4

Melting

Question 5

Liquid to gas

Answer 5

Evaporating/boiling

Question 6

Gas to liquid

Answer 6

Condensing

Question 7

Liquid to solid

Answer 7

Freezing

Question 8

Solid to gas

Answer 8

Sublimation

Question 9

Gas to solid

Answer 9

De-sublimation/Deposition

Question 10

The arrangement, movement and energy of the particles when : a solid, changes into a liquid

Answer 10

Particles in the solid gain kinetic energy and vibrate more, eventually the solid structure breaks down and forms a liquid where particles are randomly arranged and move freely

Question 11

The arrangement, movement and energy of the particles when : a liquid, changes into a gas

Answer 11

Liquid particles are arranged randomly but still close together, and they gain kinetic energy and move faster. Eventually, attractions between particles break down and they spread out, moving very fast

Question 12

The definition of : a pure substance

Answer 12

Composed of only 1 type of substance (atoms or molecules)

Question 13

The definition of : a mixture

Answer 13

Composed of 2 or more different substance
