What makes balloons float when they are full of air but not float when they are deflated?

When balloons float they have helium in it. Helium is not air, but a gas. It's lighter than air, which makes it float.

Balloons float when they are full of air because the helium or air inside is less dense than the surrounding air, creating buoyancy. When they are deflated, the balloon is denser than the surrounding air, causing it to sink rather than float. This is due to the principle of buoyancy and the difference in density between the balloon and the air.

Why do baloons float in air?
Balloons float in air because they are filled with a gas that is lighter than the surrounding air, usually helium or hydrogen. This creates a buoyant force that pushes the balloon upward, causing it to float.
Can you fill helium balloons with normal air?
No it doesn't have helium. A hot air balloon derives it's lift from heated air, which is less dense and therefore lighter than normal air. A helium balloon derives it's lift from helium, a gas which at normal temperatures is less dense than normal air. So both fly 'lighter than air' but for different reasons.
What is the difference between a full and an empty balloon?
A full balloon contains air or gas and is inflated, while an empty balloon has no air or gas inside and is deflated. This results in a full balloon being able to float or rise in the air, while an empty balloon will sink or stay grounded.
Why don't normal balloons stay in the sky?
Normal balloons are filled with helium, which is lighter than the surrounding air. This causes the balloon to float in the air. However, over time the helium escapes from the balloon, making it lose buoyancy and eventually fall back to the ground.
What does full time float position mean?
A full-time float position typically refers to a job where the employee works a set number of hours per week but is not assigned to a specific location. Instead, they "float" between different work sites or locations as needed by the employer. This can be common in industries such as healthcare or retail where staffing needs vary between different locations.

Why a lifejacket helps you float?
It's full of air that makes it buoyant
Why there is no life in dead sea n why things n living things float on its surface?
Because it is full of dissolved salt which makes the density of things lighter, and therefore makes them float.
How do you convince your younger ones that there is air all around?
A fan. You might have drop pieces of paper in the path of the fan, and query them as to what makes the paper move. Balloons are also fun--what are the balloons full of, and from where does it come?
How many cows are there in a box full of balloons?
There are no cows in a box full of balloons, as cows are animals and balloons are objects commonly used for decoration or celebrations.
How many balloons are colored red in a bag of 12 balloons?
It's a trick question, the bag was full of green baloons.
Why do chilly bins float?
yes, bins full of chilli float.... why?
How can a huge ocean liner built of steel float while a penny placed in a glass of water sinks?
Buoyancy In physics, buoyancy is the upward force that keeps things afloat. The net upward buoyancy force is equal to the magnitude of the weight of fluid displaced by the body. This force enables the object to float or at least seem lighter. In simple words, the hollow ship displaces an amount of water that is heavier than the ship. What puzzles me is how an oil tanker that is "full" of heavy oil will float----now that is a real dilema. This is what makes hot-air balloons fly and ships float.

Do milk containers float?
It depends if the carton is full or not. If the carton is empty, then it will float. If their is milk in the container, then it won't float.

The float on your lawnmower is full of petrol?
The float bowl is supposed to be full of fuel. However, if what you are saying is that the fuel doesn't stop flowing into the float bowl and causes the engine to flood, then the problem lies in the needle valve that is controlled by the float. When the float drops because the engine is "pulling" fuel, the valve will open to allow more fuel into the bowl. As the bowl fills up, the float will rise and close the valve to cut off the fuel supply. The other interpretation I can make of your question is that the float itself is full of fuel. If that's the case, the float is damaged and must be replaced.
