SUMMARY

The discussion centers on the pressure dynamics within a star-shaped balloon. It is established that the pressure inside the balloon remains uniform across all points, including the center and edges. When additional air is pumped into the balloon, there is a momentary increase in pressure at the points where air is introduced, but this difference is negligible and does not lead to significant temperature changes. The principles of thermodynamics confirm that while pressure can fluctuate during air addition, it ultimately equalizes throughout the container.

PREREQUISITES
  • Understanding of basic thermodynamics principles
  • Familiarity with gas laws and pressure concepts
  • Knowledge of balloon physics and material properties
  • Experience with pressure measurement techniques
NEXT STEPS
  • Research the ideal gas law and its applications in varying pressure scenarios
  • Explore thermodynamic principles related to gas compression and expansion
  • Investigate pressure measurement tools and their accuracy in dynamic systems
  • Study the effects of shape on pressure distribution in non-standard containers
USEFUL FOR

Physics students, engineers, and hobbyists interested in fluid dynamics and thermodynamics, particularly those exploring the behavior of gases in unconventional shapes.

I was wondering,

In a star shaped balloon, isn't the pressure inside the same in the center as it is in the smaller edges?

But let's say I also add some more air. As the air is being pumped in, wouldn't the pressure momentarily be higher in the points. If so, wouldn't their temperature be slightly higher because of thermodynamic principles?
 
Physics news on Phys.org
The pressure inside a container is always equal at all points. There will be a slight temperature change as air is added, but I doubt that any normal equipment could measure it.
 
As air is added, the pressure is higher where the air is being added (because the air is flowing), but as Danger said, the difference is typically negligible.

Your choice of example implies to me that you may think pressure can somehow be concentrated by the points. That's not how pressure works.
