There was a noise in my closet one night and it creeped me out. It scared me until I told myself that it might not be so scary if I checked it out. When I got to the closet, my heart pounding, I realized that it was just a book that had fallen off the shelf.

Maybe her old shoes had soft worn out bottoms and she slips in them. So her new shoes had more grip than her old ones so they kept her from falling.

Answer:

  1. Compress
  2. Fixed
  3. Melts
  4. Melting Point
  5. Freezing Point
  6. High
  7. Crystalline
  8. Lattice
  9. Unit cell
  10. Amorphous solids

Explanation:

Solids tend to be dense and difficult to <u>compress.</u>

They do not  flow or take the shape of their containers, like liquids do, because  the particles in solids vibrate around <u>fixed</u> points.

When a solid  is heated until its particles vibrate so rapidly that they are no longer  held in fixed positions, the solid <u>melts</u>.  

<u>Melting point</u> is the  temperature at which a solid changes to a liquid. The melting and <u>freezing point</u>  of a substance are at the same temperature.

In general,  ionic solids tend to have relatively <u>high</u>  melting points, while  molecular solids tend to have relatively low melting points.

Most  solids are <u>crystalline</u>

The particles are arranged in a pattern known  as a crystal <u>lattice</u>

The smallest subunit of a crystal lattice is the <u>unit cell</u>  

Some solids lack an ordered internal structure   and are called <u>amorphous solids.</u>
