Describe an activity to show that air flows from a region of high pressure to a region of low pressure. Class 8
Answer:
We can perform a simple activity using a balloon and a straw to demonstrate this concept.
Materials needed: Two balloons (identical), a drinking straw, rubber bands or thread.
Procedure:
- Inflate one balloon and tie it off. This balloon represents a region of high pressure.
- Insert one end of the straw into the inflated balloon and secure it with a rubber band.
- Insert the other end of the straw into the neck of the uninflated balloon and secure it as well.
- Observe what happens when you release the knot of the inflated balloon.
Observation: We will notice that air flows from the inflated balloon (high pressure) into the uninflated balloon (low pressure), causing the uninflated balloon to expand.
Conclusion: This demonstrates that air moves from areas of high pressure to areas of low pressure until equilibrium is reached.
