Question 1

describe solid state of matter

Answer 1

D A M

• closely together
• orderly arrangement
• vibrate about fixed position

Question 2

describe liquid state of matter

Answer 2

D A M

• Further away from one another
• not orderly no fixed position
• can slide over one another

Question 3

describe gaseous state of matter

Answer 3

D A M

• very far apart
• randomly arranged
• travel at random speeds

Question 4

evaporation

Answer 4

• occurs below boiling point

- particles at the surface gain enough energy to escape into surroundings

Question 5

what happens during condensation and when does it occur

Answer 5

• occurs at boiling point
• particles lose heat and move more slowly
• forces of attraction are able to hold the particles closely

Question 6

diffusion

Answer 6

particles of matter move from a region of higher concentration to a region of lower concentration .

Question 7

rate of diffusion

Answer 7

• affected by molecular mass of particles , higher Mr = slower
• affected by temperature , higher temp = more KE = higher rate of diffusion
