Two properties of a solid are definite volume and definite shape.
Particles are arranged in a neat tight, regular pattern with
almost no space between them. Particles vibrate back and forth but don’t change
positions.

The pictures above are all examples of solids. The
2nd and
3rd picture is
demonstrating that solid can expand when heated and contract when cooled. The metal ball
was the solid we were testing. At first the ball was able to fit through the ring at room
temperature. Then once we heated it over fire its molecules moved faster and
spread out causing the metal ball to expand not letting it to slide through the
ring.
