Balloon is made up of elastic material. It is blown because of pumping air into it. Now the wall of the balloon gets stressed. Stress is nothing but the deforming force per unit area. Same way pressure is also the force per unit area. Hence the pressure inside the ballon would increase and become greater than the atomospheric pressure. So, as we allow the mouth to be in open condition, the air rushes out from higher pressure region to lower pressure region.

Does water balloons hold more air than latex balloons?
Water balloons are typically made of thinner material than latex balloons, so they can hold less air in comparison. Also, water balloons are designed to hold water, not air, so they may burst if overinflated with air. Latex balloons are designed specifically for holding air and can typically hold more air than water balloons.
Why do rubber balloons lose air faster than plastic balloons?
Rubber balloons are more porous than plastic balloons, so they allow air to slowly escape through the surface more easily. This makes rubber balloons deflate faster compared to plastic balloons, which have a tighter seal and are less permeable to air.
Why do balloons come closer when air is blown between them?
When air is blown between two balloons, the air flow from the blower creates a low-pressure area between the balloons. This low pressure effectively pulls the balloons towards each other. The Bernoulli principle, which states that moving air has lower pressure, helps explain this phenomenon.
What is added to balloons and hot air balloons?
Balloons can be filled with air (don't float), or with hydrogen or helium (float because the gas is less dense). Hot air balloons use burners to heat the air so that it becomes slightly less dense than the cooler air around it, providing some lift.
What last longer helium fill balloon or hot air balloons?
Helium-filled balloons last longer than hot air balloons. Helium is a non-flammable, inert gas that does not expand or contract with temperature changes like hot air does. Hot air balloons require periodic reheating to maintain altitude, whereas helium balloons will gradually lose lift over time but can remain buoyant for days.
Why lighter than air balloons fly?
air balloons or hot air balloons fly because they fill with a very light type of air. The air is hot air.
Why does a balloon whistle when you let it go?
because when you let a balloon go, all the air comes out really fast and that's why balloons whistle when you let it go.
What is something interesting about hot air balloons?
Hot air balloons were the first successful human-carrying flight technology, dating back to the 18th century. They operate on the principle that hot air is lighter than cool air, allowing them to lift off the ground. Hot air balloons offer a serene flying experience and are a popular choice for sightseeing and recreational air travel.
Does water balloons hold more air than latex balloons?
Water balloons are typically made of thinner material than latex balloons, so they can hold less air in comparison. Also, water balloons are designed to hold water, not air, so they may burst if overinflated with air. Latex balloons are designed specifically for holding air and can typically hold more air than water balloons.
What types of hot air balloons are there?
There are traditional hot air balloons, special-shaped hot air balloons (such as animals, objects, or characters), and solar-powered hot air balloons that use solar energy to heat the air inside.
What kinds of balloons are there?
hot air balloons, colorful ones what kind of simple quesion is this!
Why do hot air balloons travel upward?
The heated air causes the whole balloon to rise. When the air inside the balloon cools down, or when the hot air is let out, the balloon goes down.
Where in the atmosphere do hot air balloons float?
Hot air balloons float because hot air displaces cool air in the atmosphere
How many balloons did Yves Klein let off?
Yves Klein let off one-thousand and one balloons.
How can the height be controlled for hot air balloons to land?
There is a valve to release hot air from the top. The amount of hot air you let out from the top is replaced with cooler air from the bottom, causing the balloon to descend.
Did they actually let up 99 red balloons in the air?
The song "99 Red Balloons" by Nena is fictional. It tells the story of 99 balloons being released into the sky, mistaken for enemy aircraft, leading to a nuclear war. In reality, this event did not occur.
Why do rubber balloons lose air faster than plastic balloons?
Rubber balloons are more porous than plastic balloons, so they allow air to slowly escape through the surface more easily. This makes rubber balloons deflate faster compared to plastic balloons, which have a tighter seal and are less permeable to air.
