States Of Matter

Question 1

Describe the movement,arrangement and relative energy of solids

Answer 1

The particles do not move but vibrate as they have the lowest energy
Particles are touching and are very close together,regular arrangement
Has the strongest forces of attraction

Question 2

Describe the movement,arrangement and relative energy of liquids

Answer 2

The particles move around in any direction and slide over each other
Particles mainly touching but some gaps.random arrangement
Forces weaker than solid

Question 3

Describe the movement,arrangement and relative energy of gases

Answer 3

The particles move around very quickly in any direction as they have the highest energy
Particles are not touching
Very weak forces as they are far apart

Question 4

Describe what happens when solids turn into liquids and vice versa

Answer 4

Solid into liquid:melting-when a solid reaches it’s melting point through enough heat
Liquid to solid:freezing-when particles lose enough energy so that they lock into place

Question 5

Describe what happens when liquids turn into gases and vice versa

Answer 5

Liquid into gas:evaporation -when a liquid reaches its boiling point
Gas into liquid:condensation -when a solid loses enough energy to start moving closer to other partices

Question 6

Describe what happens when solids turn into gases and vice versa

Answer 6

Solid into gas:sublimation-misses the liquid phase
Gas into solid:deposition-misses the liquid phase

Question 7

What does pure mean?

Answer 7

Made up of only 1 element or compound

Question 8

What does impure mean?

Answer 8

Made up of more than 1 element or compound (mixture)
