A hot air balloon might stop working if there is a leak in the balloon envelope or burner system, causing loss of hot air. Adverse weather conditions such as strong winds or turbulence can also affect its ability to fly safely. Additionally, malfunctions in the control systems could lead to difficulties in steering or controlling altitude.
A hot air balloon does not depend on thrust like an airplane does. It rises due to the buoyancy of the hot air inside the envelope, which is lighter than the surrounding air. Drag does affect the balloon's movement and control, but it is not the primary force that allows it to float.
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.
The balloon would get larger as the air pressure outside it dropped. At some height, the balloon would get large enough to burst.
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.
Turning on the burner in a hot air balloon heats the air inside the balloon, reducing its density. This decrease in density causes the balloon to become lighter than the surrounding air, which helps it to rise. The heated air adds buoyancy, allowing the balloon to ascend.
Three working forces on a hot air balloon are lift (created by hot air inside the balloon being lighter than the surrounding air), gravity (pulling the balloon downward), and drag (resistance caused by the air as the balloon moves through it).
There is a handle that you pull to close the vent that blows hot air into the balloon.
If a hot air balloon, then stop heating the air. If a lighter-than-air balloon then release some of the gas.
with out the hot air the balloon would not rise
To weigh air in a balloon, you would first need to weigh the balloon when it is empty. Next, fill the balloon with air and weigh it again. The difference in the weights would give you an approximation of the weight of the air in the balloon. However, this method would not provide an accurate measurement of the weight of the air due to factors like the weight of the balloon material and the presence of air inside the balloon.

He would heat it.
When you inflate a balloon, even on land, you pinch the mouth of the balloon shut to stop air escaping once you have run out of air. You can do the same thing underwater. Take a breath, dive under, and blow into the balloon, and pinch it when you run out of air. You could also use a snorkel, but you will need to make sure you leave enough air in your lungs to blow water out of the snorkel.

It's easy, just stop putting hot air in it.
Simple...hot air rises..
The air inside the balloon would cool down and contract, causing the balloon to shrink in size.
