with out the hot air the balloon would not rise
if you mean how the hot air in a hot air balloon makes it rise, its because hot air is less dense than cold air. when cold and hot air meet the cold air sinks thus making hot air left to rise.so when you put hot air in a balloon the air would rise. hope this helps.
One can find and book hot air balloon rides in Niagara on the 'Balloon Over Letchworth' website. One can also find such balloon rides listed on 'Trip Advisor'.
For as long as it can provide hot air.
The Hot air balloon wouldnt fly strait
the mechanical advantage of a hot air balloon is this that we can use it in many good ways like it is for individual flight for every one, and can be use at any time but it depends on the air resistance + gravity because if the gravity is low the hot air balloon would fly far and far in the air and if the gravity is hifgh it would unable to fly and in air resistance if the air is high it would be difficult for a hot air balloon to fly and if air resistance is low it would be difficult for hot air balloon to fly in the air
A hot air balloon needs a flame to heat the air inside the balloon, making it less dense than the surrounding air. This temperature difference creates lift, allowing the balloon to float upwards. Without the flame, the air inside the balloon would cool down and the balloon would descend.
He would heat it.
If the burner fails or runs out of fuel, the hot air in the balloon (that gives it lift) would cool and the balloon would come down to earth.
The weight of a hot air balloon varies depending on its size and design. On average, a small hot air balloon can weigh around 250-400 pounds (113-181 kg) without passengers or fuel.
A hot air balloon needs a burner to heat the air inside the balloon. When the air inside the balloon is heated, it becomes less dense than the surrounding air, causing the balloon to rise. The burner is used to maintain the temperature inside the balloon as needed for lift.
Heating the gas inside the balloon causes it to expand and become less dense than the surrounding air. This creates a buoyant force greater than the weight of the balloon and its contents, causing the balloon to rise.
