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
  • No definite shape; no definite volume
  • No definite shape; 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 flower-shaped cake is made by pouring it into a flower-shaped mold. Which property of matter is illustrated by this process?
  • 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.
