If an ordinary balloon is filled with air and pushed under water what will happen?
It should float up. Air is less dense than water, so it will float.
Why heating the air allows a hot air balloon to float?
Heating the air inside the balloon makes it less dense than the surrounding air, causing the balloon to float. As warm air is lighter than cool air, the balloon rises because of the difference in densities. This creates an upward force, known as buoyancy, that allows the balloon to float.
Does a balloon float or sink on water and why?
A balloon filled with air will float on water because it is less dense than water. The buoyant force acting on the balloon allows it to float.
Can you make a balloon that float in air?
Yes, a helium-filled balloon will float in the air because helium is less dense than the surrounding air. When filled with helium, the balloon experiences a buoyant force that causes it to rise and float.
Why doesnt a balloon float with your air?
A balloon does not float with your breath because the air you blow into it is denser than the surrounding air. To make a balloon float, you need to use a lighter gas, such as helium, which is less dense than the surrounding air and creates enough lift to keep the balloon suspended.
How long will balloons float filled with exhaled air?
When a balloon is blown up by mouth, it will not float, but fall to the ground. This is because the air inside is the same density as the air outside. For a balloon to float up into the air, it must be inflated with a gas that is lighter than air - such as helium.
Why can't a hot air balloon float in outer space?
A hot air balloon requires air to generate lift. In outer space, there is no air or atmosphere, so there is nothing for the hot air balloon to displace to generate lift, causing it to be unable to float.
Why wont a blloone with carbon dioxide float?
To float in air, the density of the balloon (divide the combined mass of balloon + contents by its volume) must be LESS than that of the same volume of air. If the gas inside the balloon has a greater density than air, the combined object (balloon + contents) won't have less density than air, either.

Why does an air balloon not float?
A hot air balloon floats because the air inside is heated, making it less dense than the cooler air outside. This creates a buoyant force that lifts the balloon. If the air inside the balloon is not heated, it will not be less dense than the surrounding air, and the balloon will not float.
In a hot air balloon air is heated by a flame Explain how this enables the balloon to float?
Heating the air inside the balloon makes it less dense than the surrounding air, causing the balloon to float upwards. As the air inside the balloon cools, it becomes denser and the balloon descends. The pilot can control the altitude by adjusting the temperature of the air inside the balloon.
How does a helium balloon float but not a balloon filled with air?
Helium is a lighter element compared to air, helium also has fewer molecules than air.
How does a hot air balloon float even though it is so heavy?
Well the basic answer is that when the balloon is 'floating' it is not heavy. The hot air inside the balloon is less dense and therefore lighter than the ambient air. The hotter it is, the lighter it is. When the weight loss of the air inside the balloon is equivalent to the weight of the balloon and equipment, passengers, etc., then it will float. The weight reduction of heated air is quite small which is why balloons have to be so big.
