General Instructions

Step 1: Select and Reflect

Select one of the following lessons below and reflect on how they are applied in practical settings.

• Gas Pressure
• Relating Pressure, Volume, Amount, and Temperature: The Ideal Gas Law
• Stoichiometry of Gaseous Substances, Mixtures, and Reactions
• Effusion and Diffusion of Gases
• Non-Ideal Gas Behavior

Step 2: Respond

Using supporting data to back your arguments, prepare a 500-600 word written piece which discusses any one of the following: 

• Describe some of the practical applications of using pressurized gas to power machines and the safety considerations for working with high gas pressures in industrial settings.
• Describe how changing the temperature of an ideal gas affects the relationship between its pressure, volume, and amount.
• Discuss why some gases diffuse more readily than others and how temperature affects the rate of diffusion.
• What are the limitations of real gases compared to ideal gases, and how can we account for non-ideal behavior in our models?
• Given that the Ideal Gas Law equation is PV = nRT, what is the density (ρ) of a gas with a pressure of 1.2 atm, a molar mass of 32 g/mol and a temperature of 25°C?

Step 3: Share 

To share your work, click on the “Add a new discussion topic” button under this post and paste your work into the “Message” box. Make sure to reference others’ intellectual property when necessary. All references should follow 7th Edition APA formatting.

Step 4: Interact 

To complete the activity, you will need to reply to at least two posts made by your peers in a respectful and professional manner. Be sure your post engages your peers' ideas by including a reflection on their comments, sharing ideas on other potential difficulties and parties involved, or asking thought-provoking questions. If a peer comments on your posting, please reply. To post a reply, click “Reply” on a particular discussion, write your feedback and then click on “Post to forum.”

OPTIONAL Step 5: Interact (10 minutes)
