Classify Matter

By studying the terms and direction of arrows in the diagram, you can determine that--

• State 1 is gas. State 2 is a solid. State 3 is a liquid.

• State 3 is a solid. State 2 is a liquid. State 1 is a gas.

• State 1 is a solid. State 2 is a liquid. State 3 is a gas.

• State 1 is a liquid. State 2 is a solid. State 3 is a gas.

For homework, Mrs. Smith asked her students to make a drawing of common examples of solids, liquids, and gases. Alex drew this picture of a glass filled with soda. Alex things he should earn full credit for the assignment because--

• it is impossible to draw a picture of gas.

• solids, liquids, and gases never exist in the same place at one time.

• the ice is solid, the soda is liquid, and the carbonation is gas.

• solids, liquids, and gases are uncommon in nature.

Why were these substances placed into these groups?

• One group is man-made; the other is natural.

• One group conducts electricity; the other insulates.

• One group is permanent; the other cycles through nature.

• One group is inexpensive; the other is costly.
