Text reading skill: preview and ask questions
Instructions: Find Chapter K section 3 on page 55. Read the headings (in red) in this section and write a what or a how question for each red heading. Make sure to end your question with a question mark. Good readers know what they will be reading and constantly ask questions about what they read.

21- What is the relationship between gas pressure and gas volume?
22- Explain why increasing the temperature of a gas in a closed, rigid container causes the pressure in the container to increase.
23- Suppose it is the night before the city parade, and you are in charge of inflating the balloons. You just learned that the temperature will rise 15oC between early morning and the time the parade starts. How will this information affect the way you inflate the balloons? (2 pts)
