Introduction to Chemistry: Arrangement, distance, and attraction between particles
1.0 Introduction to Chemistry
1.5 Arrangement, distance, and attraction between particles
To find out about the arrangement, spacing and attraction between particles of matter
Questions 1.5 
From the kinetic theory (Section 1.4) and your own experience with matter:
- Are the particles in liquids and gases strongly held together?
- Give a reason for your answer.
- Rank solids, liquids and gases in the order of their density ("heaviness"). Most dense -- Less dense -- Least dense --
- Rank solids, liquids and gases in the order of closeness of their particles. Close --Closer --Closest -- (c) Give a reason for your answer to 2(b).
- Rank gases, solids and liquids in the order of strength of attraction between their particles. Weaker --Weak --Strong--
-
- In which physical state is the arrangement of particles regular?
- Give a reason for your answer.
Answers to Questions 1.5 
In life
Air is very soft, of very low density and we can freely move through it. Water is fairly soft, has low density and fairly easy to move through. But solids are generally hard, of high density, and we can hardly move through them.
These properties give us a an idea about the spacing and attraction between particles in solids, liquids and gases.
