Beginner's Guide to Rockets
Equation of State (Ideal Gas)

Subject Area: Physics, Algebra I

Grade Level: 9-12

National Mathematics Standards:

  • Apply integrated mathematical problem-solving strategies to solve problems from outside mathematics.
  • Reflect upon and clarify their thinking about mathematical ideas and relationships.
  • Follow logical arguments.
  • Use and value the connections between mathematics and other disciplines.
  • Understand the logic of algebraic procedures.

National Technology Standards:

  • Research Tools - Use content-specific tools, software and simulations (e.g., environmental probes, graphing calculators, exploratory environments, Web tools) to support learning and research.
  • Problem-Solving and Decision-Making Tools - Routinely and efficiently use on-line information resources to meet needs for collaboration, research, publications, communications, and productivity.


After reading an explanation from a NASA Web-based textbook, you will demonstrate your understanding of the Equation of State for an ideal gas by computing the gas constant from air properties.

Beginner's Guide to Rockets is a "textbook" of information prepared at NASA Glenn Research Center to help you better understand how rockets work. Click Beginner's Guide Index to access the list of slides. Open the slides called Air Properties Definitions (with text) and Equation of State and read the definitions. Using the information shown at Equation of State Problems and additional given information, complete the problems designed to demonstrate your ability to determine and use the gas constant from the Equation of State.


You, or you and your partner(s), will be evaluated on the accuracy or feasibility of your answers.


You will demonstrate the ability to apply information found on the World Wide Web to physical data.
