• Diagram A illustrates gas particles.
• Diagram B illustrates gas particles
• Diagram C illustrates gas particles.
• None of these illustrates gas particles.

The drawing shows how a solid piece of matter can be magnified. Which of the following tools would be the best to use to generate this degree of magnification?

• A magnifying glass
• A microscope
• A telescope
• A prism

5. In the diagram, State of Matter C is a gas. This means that which of the following statements is true about this state of matter?
