15
Q

How are liquids arranged?

A

Randomly. The particles are still close together. There are some gaps, but about half the particles still touch one another.

16
Q

How are gases arranged?

A

Randomly. The particle are far apart from one another.

17
Q

How do solids move and how fast are they?

A

They vibrate around fixed positions. No free movement.

Slowly vibrate cannot move freely

18
Q

How do liquids move and how fast are they?

A

Freely and randomly. They can change places easily even thought they are close together.
Faster movement

19
Q

How do gases move and how fast are they?

A

Freely and randomly

Very fast movement

20
Q

Solids Liquids and Gases. How strong is the attraction between them?

A

Solids VERY STRONG Liquids STRONG Gas VERY WEAK
