The gas pressure inside an inflated rubber balloon
is always greater than the air pressure outside
because the pressure inside balances the atmospheric pressure as well as the pressure resulting from the walls of the balloon.
What is the relation between inside pressure and outside pressure of an inflated balloon?
The pressure inside the balloon is higher than the pressure on the outside
. A simple and intuitive way to look at it is if you poke a hole in the balloon, the air flows out. And the direction of airflow is always from higher to lower pressure.
When a balloon is inflated Where do you think the air pressure is higher inside or outside?
Answer: The
pressure inside the balloon is higher than the pressure on the outside
. A simple and intuitive way to look at it is if you poke a hole in the balloon, the air flows out.
What is the pressure inside a balloon?
One experiment shows that the balloon reaches a relatively constant pressure of
810 mmHg
until it gets close to its maximum elasticity point and then increases to 820, 830 and finally 840 mmHg when it pops.
Is the pressure inside a balloon greater than the air pressure outside?
The gas pressure inside an inflated balloon is
always greater than the air pressure outside
.
What happens if you inflate the balloon more?
When you inflate a balloon, you’re actually putting gases, in this case mostly helium, into an elastic container. As you add more gas, the pressure inside the balloon increases, and in response,
the balloon expands
… … As you go higher into the atmosphere, the air becomes thinner, and the atmospheric pressure drops.
What happens to a balloon when pressure increases?
As balloons rise, air pressure around them diminishes. When the ballon is made of elastic material,
it expands because of the excess pressure inside
. Its volume increases and its internal pressure decreases.
Where is pressure inside a balloon the highest?
The gas pressure inside an inflated rubber balloon is always greater
than the air pressure outside
because the pressure inside balances the atmospheric pressure as well as the pressure resulting from the walls of the balloon.
How does gas in a balloon act when heated?
When gas molecules are warmed,
their average kinetic energy also increases
. This means they move faster and have more frequent and harder collisions inside of the balloon. When cooled, the kinetic energy of the gas molecules decreases, meaning they move more slowly and have less frequent and weaker collisions.
Where is the most pressure in a balloon?
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.
Why does air escape from a balloon?
As the surface stretches to inflate, the surface becomes so thin in some places that tiny, microscopic holes result.
Air molecules are able to slowly diffuse
, or escape, via the surface of the balloon, or tiny holes in the know you tied to keep the darn thing closed.
When a balloon is inflated does pressure increase?
The arrows show that the pressure of the air inside pushing outward and the pressure of the air surrounding the balloon pushing inward are all the same strength. Next we warm the air in the balloon (Fig. 2). The ideal gas law equation tells us that the pressure of the air in the balloon
will increase
.
Where does the air go when a balloon deflates?
Remember, you’re looking through a microscope. But over time, the air or helium inside of the balloon will make its way out of the
porous walls
and you’ll be left with your deflated balloon. This is called “permeation.”
How much air pressure does it take to inflate a balloon?
In order to blow up a normal balloon apparently you need
1 psi pressure
to overcome the elastic forces of the balloon (i.e. a normal balloon has a higher pressure inside it).
What keeps a balloon from expanding?
Gas pressure
is the pressure that results from collisions of gas particles with an object. Inside the balloon, the gas particles collide with the balloon’s inner walls. It is those collisions which keep the balloon inflated. If the gas particles were to suddenly stop moving, the balloon would instantly deflate.
What happens to air pressure in a balloon when it floats into the sky Why?
A measured amount of helium is put into the balloon that will give it enough lift to get off the ground and ascend to the desired float altitude. As the balloon rises,
the gas inside the balloon expands because the atmospheric pressure surrounding the balloon drops
.
