A hot air balloon floats because the air inside the balloon is heated, making it less dense than the surrounding cool air. This causes the balloon to be buoyant and rise up. The weight of the balloon is distributed across a large surface area, allowing it to float even though it may be heavy.

How does a hot air balloon float even though it is so heavy?
A hot air balloon floats because the heated air inside the balloon is lighter than the cooler air outside. This temperature difference creates a buoyant force that lifts the balloon. The total weight of the balloon and its contents must be less than the weight of the air it displaces in order for it to float.
Can a lead balloon float?
No... it wouldn't even survive the conditions of the upper atmosphere, unless it was a very tough balloon.. even if it could I'm assuming eventually the atmosphere would reduce to a point where it was as dense as helium or hydrogen (the gas I'm assuming would make your balloon float) and your balloon would stop anyway at a maximum altitude. Either way.. after that, the balloon would have to break away from Earth's gravity (not easy) and then somehow cover 382500km or so to get to the Moon itself..
What happens when you rub a balloon with wool and the other with silk?
Rubbing a balloon with wool will transfer electrons from the wool to the balloon, giving the balloon a negative charge. Rubbing a balloon with silk will transfer electrons from the balloon to the silk, giving the balloon a positive charge. These charges create static electricity and can cause the balloon to stick to other objects or even repel other charged objects.
Why does a balloon have mass?
A balloon has mass because it is made of matter, specifically latex or rubber. Even though a balloon filled with helium or air may feel light, it still has mass, which is the amount of matter it contains.
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 is the weight of water displaced by a massless balloon?
No real object is massless. Even a balloon has the mass of the balloon plus the mass of the entrained gas.But if the buoyancy of the entrained gas (hydrogen, helium) allows the balloon to float away, then it will displace no water. Even so, it still has mass.
Is Jupiter really heavy?
Yes. Even though its a planet of condensed gas its heavy.

Why do people float when swimming even though gravity is pulling them down?
b/c fat floats. it makes it harder to float if there no fat. And it requires skill

What enables a swimmer to float even though his body uncontrolled sink in water?
Motion, continous motionmakes it possible for the body to float. An example is the bicycle, when it stops its motion, it fall.
Is it the weight that makes things float?
No, it is the density of the object compared to the density of the fluid it is placed in that determines if it will float or sink. An object will float if it is less dense than the fluid it is in, regardless of its weight.
If an object floats in oil then does it float in water?
Not necessarily. An object's ability to float in a liquid depends on the density of the object compared to the density of the liquid. Even though an object may float in oil, it may not float in water if the object is more dense than water.
Could you be pregnant even though you are bleeding heavy?
I'm pretty sure you can't if you have your period
