long live the rick roll on wiki.
Just the density difference between the balloon and surrounding atmosphere is so great that the balloon is able to lift itself and people.
because the air inside the balloon is heavier than the air outside in the other layers of the atmosphere
No, the Moon has no atmosphere. The hot air does not have the colder air to be lighter than! Such a balloon would work on Mars or some moons of the larger planets which have some kind of an atmosphere.
No, a hot air balloon cannot leave Earth's atmosphere. Hot air balloons rely on the Earth's atmosphere to provide lift for their flight. They are designed to operate within the troposphere, the lowest layer of Earth's atmosphere.
No, because the atmosphere would pop the balloon.
No. The atmosphere of Mars is too thin.
NASA is thinking it can.
As the balloon ascends into the atmosphere, the air pressure surrounding it decreases, causing the gas inside the balloon to expand. Eventually, the gas inside the balloon will expand so much that the balloon will burst or pop. Pieces of the balloon will then fall back down to the ground.
The first hot air balloon to take people up was in 1783 in Paris, France.
A hot air balloon rises due to the principle of buoyancy. As the air inside the balloon is heated, it becomes less dense than the surrounding air, causing the balloon to float upwards. This effect is similar to how a helium balloon rises in the atmosphere.
The pressure outside the balloon doesn't change when the balloon rises. By a balloon rising, I assume that air is being placed into the balloon. As the balloon fills with air, the pressure inside the balloon will increase. Since the balloon can stretch, the increasing pressure against its inner walls will cause it to rise, or more correctly put, expand. Eventually, the balloon will be stretched to its fullest capacity if more air is placed inside it. When it pops, the bang you hear is the high pressure of the atmosphere inside the balloon equalizing with the lower pressure of the atmosphere outside the balloon.
Particles in the air are heated by a burner in the hot air balloon, causing them to expand and become less dense. This creates a pressure difference between the inside and outside of the balloon, allowing it to rise and float in the atmosphere.
