Air has a certain density. A hot air balloon heats air inside the balloon which causes it to become less dense. This is because the hotter something is, the more space it takes up. Less dense things float on top of more dense things (think of oil on water). You get enough less dense hot air, and the balloon will float up on top of the cold, dense air.

How do the vents work on a hot air balloon?
the vents work because of the heat which can make the hot air balloon go up
How do vents work on a hot air balloon?
the vents work because of the heat which can make the hot air balloon go up
What do you think will make the balloon move faster?
Increasing the air pressure inside the balloon or decreasing the weight of the balloon are two factors that can make a balloon move faster. Additionally, reducing air resistance by using a streamlined shape or reducing the size of the balloon can also help increase its speed.
How does air make a balloon fly?
air is heavier than balloon, air rises
Why do hot air balloons work?
Hot air balloons work by heating the air inside the balloon with a burner, which makes the air less dense and causes the balloon to rise. This is because the hot air inside the balloon is lighter than the cooler air outside, creating a buoyant force that lifts the balloon. By controlling the temperature of the air inside the balloon, the pilot can control the altitude of the balloon.
What happens to balloon after being in the freezer for a few hours?
That would depend on whether the balloon was empty, full of air or full of water and as you have not told us which we can not help you. When asking questions please make them specific if you want us to help.
Why can air balloon rise to the sky?
it can rise because of the helium and the gases help make it rise to the sky
Why Would a hot air balloon pilot heat or cool the air in the balloon to make it rise?
Heating the air makes less air take up the same space, so the air inside the balloon is lighter than the surrounding air. The pilot turns off the burner to help the balloon to maintain the current altitude or to descend.
How do balloon rockets work?
Balloon rockets work by utilizing the principle of action and reaction. When air is released from the balloon, it creates a force that propels the balloon in the opposite direction. The escaping air creates thrust, pushing the balloon in the direction opposite to the airflow.
What are reasons why a hot air balloon won't work?
They do work.
Why does a balloon need hot air?
A balloon needs hot air to make it rise because hot air is less dense than cold air. When the air inside the balloon is heated, it becomes lighter and causes the balloon to lift off the ground and float in the air.
How would you raise a hot air balloon above some trees?
To raise a hot air balloon above trees, you would need to increase the heat in the balloon by firing up the burner. The hot air will make the balloon lighter than the surrounding air, causing it to ascend. Piloting the balloon to catch different wind currents can also help in maneuvering it safely above the trees.
