Why does my 'prof' says that pressure inside a rubber balloon is greater than the air pressure outside

[From: ] [author: ] [Date: 12-12-23] [Hit: ]
does this principle have something to do with it? please elaborate if you could. thanks!!-because if the pressure inside is less then the ballon will explode ,remember that pressure is force divided by area (P=F/A) ,......
we are currently studying fluid dynamics, we have just finished bernoulli's principle. does this principle have something to do with it? please elaborate if you could. thanks!!

because if the pressure inside is less then the ballon will explode ,remember that pressure is force divided by area (P=F/A) ,so a greater pressure means a greater force ,hence if there is high pressure inside then the resutant force is outside and not inside hence the ballon cannot explode but if you bring the ballon at a thousand feets below water ,it will be the reverse and then the ballon will explode because the pressure also varies with height from the formular P=density of water x gravity x height
SO YOUR PROF IS CORRECT
This reasoning has nothing to do with bernoulli ,its just common physics you need to know and most important that pressure varies with height .Also remember that if the pressure inside your body was less than the atmospheric pressure outside then you will die ,if you want to try ,try and go 200 m down a sea and you will see real physics lol no joke its real and if you want your body to explode ,try and go 200 meters above ,i mean in the atmosphere and you will start hearing your ears will pain like in an airplane but airplanes can pressurize the cabin to maintain body pressure hence you cannot die but if you open the door it will be the reverse

gd luck with your final exams

The most direct reason is the tension in the surface. The balloon is stretched, & trying to shrink. Because shrinking would reduce the volume of the enclosed air, that constitutes a force on the air, inward, which in turn is an additional pressure on that air, just like a piston into a cylinder.

The air inside a balloon is subject not only to the air pressure outside, but also to the pressure exerted by the stretched rubber. The "bang" when a balloon is popped is caused by the sudden expansion of the air inside as this pressure is removed. Try blowing up a balloon compared with just breathing normally.
