        Disorderly / Random
        
        Quite close together
        
        Move about freely by sliding over one another
      - Gases
        
        Weak/Negligible
        
        Disorderly / Random
        
        Far apart
        
        Move freely in all directions at high speeds

    - - The particles are held by strong attractive force, so they can only vibrate at their fixed positions
        
        The particles can only vibrate at their fixed positions.
        
        The particles are closely packed together, so there are limited spaces to squeeze them further.
        
        The particles are closely packed together, so the mass per volume ratio is relatively high.
        
        When a substance is heated, its particles gain energy to vibrate more vigorously
        
        and push each other away, so the distance between them increases and hence the
        
        volume occupied by the particles increases.

        and hence have an orderly arrangement.

    - - The attractive forces between the particles are moderately strong, so they can
        
        The attractive forces between the particles are strong enough to hold them in confined spaces,
        
        so they cannot move freely in all directions
        
        The particles are quite closely packed together, so there are limited spaces to squash them further.
        
        When a substance is heated, its particles gain energy to vibrate more vigorously
        
        When a substance is cooled, the particles lose energy. As a result, their motion
        
        between them decreases and hence the volume occupied by the particles
        
        decreases.

        decreases and they come close to one another. As a result, the distance
        
        between them decreases and hence the volume occupied by the particles
        
        decreases.

        the volume occupied by the particles increases.
      - only move about freely by sliding over one another in confined spaces and
      - hence have a disorderly arrangement.
