Discussion: What causes pressure inside the bike tire?

Please set your computer aside briefly (do not close this page) and join the classroom discussion that your teacher is going to moderate.

Note: If your teacher did not initiate the discussion yet, please start answering the first question below as you are waiting.

 

 

Referenced Questions

These questions were answered in the previous steps. They are provided here for your reference.

How do you think the value of "pressure" is calculated inside this bike tire? (min. 3 sentences)

Tip: Remember that pressure (P) is defined as F/A (force divided by the surface area). Try to think about these two questions: (1) "what is the surface area in this model?" and (2) "what applies force to the surface area in this model"?

Questions

Please answer the questions below.

If the discussion has not started yet, start answering this question: Can you think of any objects that take advantage of gas pressure similar to the bike tire?  List as many as you can and explain why.

 

Before moving on, please reflect on the classroom discussion briefly: What creates pressure inside a gas container? Where does the force come from? Why do we observe the fluctuations (i.e. oscillations or relatively stable up-and-down changes) in the image below? (min. 3 sentences).
