Journal: Air Pressure and Wind
If you have ever inflated a balloon and then let the air flow out of it quickly, you have likely felt the movement of air that this causes. Think of an inflated balloon and create a journal entry to answer these questions:
- When the balloon is inflated, where is air pressure greatest, inside it or outside it? (Hint: the air inside the balloon is exerting force on the inside walls of the balloon and the air molecules are trapped in a confined space.)
- When the balloon has deflated, is there any difference between the air pressure inside and outside of the balloon? Explain.
- When a balloon is deflating, why does air leave the balloon?
- Using the example of the balloon, explain what causes wind to blow.
Please write your journal entry in the Journal template. You will be prompted at the end of this unit to turn in all of your journal entries.
