How does a hot air balloon return to Earth's surface?

A hot air balloon comes down when less lift is provided by reducing balloon air temperature to control descent.


How can you bring a Hot balloon lower?

To bring a hot air balloon lower, the pilot can release hot air by pulling a cord that opens the top of the balloon envelope, allowing the heat to escape. This causes the air inside the balloon to cool down, which decreases the overall lift and brings the balloon closer to the ground.


How does a hot air balloon come down?

In rising, a hot air balloon works the same way as a helium balloon : the hot air inside is less dense than the surrounding air outside the balloon. The heavier outside air pushes below the balloon and forces it upward. To come down is easier in a hot air balloon. Unless it is continually reheated, its temperature reverts to that of the surrounding air and the balloon settles back to the Earth under its own weight. Vents that release the heated air (like venting helium in a helium balloon) is an alternative to increase the speed of descent.


What is one way you can demonstrate gravity here on earth?

One way to demonstrate gravity on Earth is by dropping an object and observing it fall towards the ground due to the force of gravity pulling it down.


How do hot air balloon pilots get their balloons back to earth?

Hot air balloon pilots control the descent of the balloon by releasing hot air and using vents to control the descent rate. They aim to land in a suitable location, often communicating with a ground crew to assist in the landing process. Once on the ground, the crew helps to pack up the balloon for transport back to the launch site.
