If you are aware that flow occurs only from a higher pressure to a lower pressure, then the balloon demonstration must have startled you.
This is because according to the demo, the smaller balloon is under high pressure. How is this even possible ?
Sucks big time right ? Its so hard to initially inflate the balloon,! But once you get going, its an easier task to handle. Here’s an intuitive explanation :
Pressure is really the force that molecules exert on the surface.
When you make that initial blow, you are adding a significantly large number of molecules into the balloon. (think of it as adding a lot of people in a very small room ) And as a result, the molecules exert a high pressure.
But once the balloon is inflated, the molecules have lot of room to move around, so they do not do around bombarding the surface that often. Hence the decreasing pressure.
( the rate at which room size increases is more than sufficient enough to accommodate the people in it )/
Variation of pressure v/s radius
This goes by the name - Two balloon experiment. Click here for a more technical explanation.
** DO TRY THIS AT HOME
I encourage you to try this at home to truly appreciate the demonstration. If you have only balloon, then inflate it fully, and then release it by holding the balloon by its neck;
Feel the pressure of the air that is coming out. ( If will increase as the balloon size decreases )
Have a great day!
Bruh this is some sci-fi shit. Fucking time crystals
