Module 8: Chapter 8: Gases Discussion
This discussion aligns with the following Module 8: Chapter 8: Gases objectives:
- Define the property of pressure (CLO1)(CLO3)
- Describe the operation of common tools for measuring gas pressure (CLO1)
Stoichiometry of Gaseous Substances, Mixtures, and Reactions (8.3)
- State Dalton’s law of partial pressures and use it in calculations involving gaseous mixtures (CLO1)(CLO2)
Effusion and Diffusion of Gases (8.4)
- Define and explain effusion and diffusion (CLO1)
- State Graham’s law and use it to compute relevant gas properties (CLO1)(CLO2)
The Kinetic-Molecular Theory (8.5)
- State the postulates of the kinetic-molecular theory (CLO1)
Non-Ideal Gas Behavior (8.6)
- Describe the physical factors that lead to deviations from ideal gas behavior (CLO1)
- Explain how these factors are represented in the van der Waals equation (CLO1)
- Define compressibility (Z) and describe how its variation with pressure reflects non-ideal behavior (CLO2)

Your replies must be more than a simple phrase like "I agree" or "I like your answers". Replies should reflect why you agree or like what has been posted. Your replies must reflect a genuine effort to engage your fellow classmates regarding the comments provided or the problem that has been solved. Please think about the questions and your peers' responses and reply thoughtfully and courteously, according to netiquette rules. Use good English grammar, correct punctuation, and complete sentences. While the posts will mostly be judged by their thoughtfulness and completeness, I reserve the right to take off points for grammatical errors, especially if they interfere with the clarity of your post.
Your initial posting is due on Monday by 11:59 pm CST. Your responses to 2 of your classmates are due on Saturday by 11:59 pm CST.
