__ States of Matter __ (Copy the following as notes.) Solids A. Solids don't spread out in a container. B. A solid has a definite shape and a definite volume. C The particles in a solid are closely packed and locked in position, so they can only vibrate. D. When a substance freezes, the particles in the liquid move so slowly that they begin to take on fixed positions. E. Sublimation occurs in some substances that change directly from a solid to a gas with enough thermal energy. (Dry Ice)

Liquids A. Liquids take the shape of the bottom and sides of a container. B. A liquid has a definite volume, but no shape of its own. C. In a liquid the particles are closely packed, but are loosely connected and move/slide past one another. D. In melting, the particles in a solid vibrate so fast that they break free from their fixed positions.

Gases A. A gas fills the container holding it. B. A gas has no definite volume or shape. (Squeeze and empty plastic bottle with the top on.) C. In gases, the atoms and molecules are free to move independently, colliding frequently. D. Vaporization takes place when the particles in a liquid gain enough energy to move independently, forming a gas. E. Condensation occurs when a substance loses thermal energy and changes from a gas to a liquid. (like on a mirror near a shower)
