The air would escape through the mouth causing the balloon to DEflate
There is not a PICC line with an inflated balloon for placement.
You did
There is no difference at all if the balloon is not inflated or inflated with air.
Natural air is always a mixture, and more or less homogenous in its major constituents. However, if the balloon was inflated by mouth, it will have less oxygen and more carbon dioxide than the air outside the balloon, which is also a mixture.
electricity well then flow
The volume of the balloon decreases
Helium goes into a balloon to make it float.
The elastic property of the balloon. The balloon stretches when inflated, and squeezes the gas filling the balloon.
What keep balloon inflated is not the molecular forces but the kinetics energy of the gas molecules made the molecules to bump and create the pressure inside the balloon.
An inflated balloon bursts if it is pressed hard because the molecules inside the balloon squeeze when it is pressed hard and air exerts pressure so the balloon bursts and let the air molecules escape from the balloon.
i probably wouldn't say the air had potential energy just that an inflated balloon has potential energy.
I'd say that an inflated balloon would be strain, but could you specify what potential energy? Chemical potential? Gravitational potential?
