because of Archimedes's principle
The force that lifts a hot air balloon is called buoyancy.
Gravity (weight), Thrust,, Air Resistance (drag), and Lift.
We know from the ideal gas laws that when you heat a gas under constant pressure, it will expand. (In a hot air balloon, the air that is heated is not in a rigid container, but in a balloon that expands with the expanding gas; the pressure it is under is only the atmospheric pressure.) The expanded gas will then have a lower density and will therefore be bouyant in air, and therefore able to lift a balloon.
when you fill a balloon with air the air makes pressure. the air pressure maximizes the balloon fabric allowing the balloon to expand.
Balloon will not fill up the full bottle in this experiment as the air is restricted by the walls of the balloon. Balloon is a solid so the air will take its shape.
Because the hot air balloon will keep on going up because the hotter the air gets the higher the hot air balloon will go!
The force that lifts a hot air balloon is called buoyancy.
If you visit the Ballon Ride US website, you may book hot air balloon flights for different areas within the United States. Prices range from $160 to $225 USD per person.
One can find hot air balloon rides in Texas on AirTexasBalloon. AirTexasBaloon offers hot air balloon rides in Houston Texas. They also offer private charter flights to other locations in Texas.
The air escaping out of the nozzle has momentum and creates a force on the balloon. According to the laws of motion, every action has an equal and opposite reaction; the balloon pushes the air out bacwards and the air pushes the balloon forward.
Hot air balloons, unlike zeppelins, are not intended to be used for long-distance or long-duration flights, and they do not have toilet facilities. If you are planning to go up in such a balloon, try to use a toilet on the ground, first.
Gravity (weight), Thrust,, Air Resistance (drag), and Lift.
If there is warm air in the balloon, cooler air makes the balloon rise and if there is cold air in the balloon warmer air makes the balloon fall.

Air= air in balloon solid= balloon and basket
This is Newton's Third Law: For every action, there is an equal and opposite reaction.
D: The hot air inside the balloon becomes less dense than the air outside the balloon.
