Why does a balloon expand when you add air to it?

Why does a balloon expand when you add air to it?

Air molecules collide into the balloon with the same energy inside and outside the balloon. These molecules now collide into the balloon with more energy resulting in increased pressure. The increased pressure causes the balloon to expand.

What is the pressure inside a balloon which is inflated in a single breath of 3.5 l radius of balloon 9 cm?

Hence, the pressure applied to the balloon is 140 N/m².

What is the pressure inside a balloon which is inflated?

4 Answers. For an inflated and tied balloon, the inner and outer pressures aren’t equal. The inner pressure is higher by an amount 2γ|H|, where γ is the inflated balloon’s surface tension and H is its mean curvature (which is −1/R for a sphere). This is called the Young-Laplace equation.

Which balloon has more pressure?

Then the pressure drops as we continue to inflate the balloon. So the pressure inside the small balloon is greater than the pressure inside the large balloon. We experience this when we blow up a balloon: the first stage is the hardest, and once the balloon has inflated a little, the task becomes much easier.

What happened to the two small balloon as you push up the big balloon at the bottom?

ANSWER↓ The lower pressure balloon will expand. So, when the valve is opened, the smaller balloon pushes air into the larger balloon. It becomes smaller, and the larger balloon becomes larger.

What might happen if you make a call using a pointed object to any of the two small balloons?

Answer. any of the two balloons will pop if you make a hole using a pointed object.

Why do balloons shrink after a few days?

The lighter helium gas molecules leave the balloon faster than the heavier nitrogen and oxygen molecules can enter the balloon. Over a period of time, the balloon shrinks! Odd as it may seem, had the balloon been filled with a gas heavier than the gases in air (argon, for example), the balloon would eventually expand.
