• It is anything that occupies space and has mass.

• Its particles are moving all the time.

• It is anything that has density.

• Its particles have no spaces between them.

Which of the following CANNOT be considered as matter?

• air inside the balloon

• water in a jar

• sound hear from cell phone

• ball floating in a river

Which of the following conclusions is supported by the above diagrams?

• Gas particles have less energy than solid.

• Solid particles are more compact than liquid.

• Liquids have a definite shape and definite volume.

• Only solid particles can scatter in a medium.

Which of the following characteristics is NOT consistent with the concept of the nature of matter?

• The particles of matter cannot diffuse.

• Particles of matter are moving all the time.

• The particles of matter attract each other.

• These particles have spaces between them.

Which properties characterize a gas?

• Definite shape; definite volume

• Definite shape; no definite volume

Based on the diagram, why can a liquid be poured and assume the shape of its container?

• The particles can move freely to all parts of the container.

• Particles have higher average kinetic energy but weak intermolecular forces.

• The particles are still close together, but they can move about freely and change positions.

• The particles don’t move freely because they are held together by strong forces of attraction.

• A liquid has definite shape and volume.

• A solid has a definite shape but not a definite volume.

• A solid takes the shape of the container into which it is placed.

• A liquid has no definite shape; it takes the shape of the container.
