Warm air is heavier than cold air so it rises up.

Why the hot air balloon needs hot air to make it rise?
Hot air balloons use hot air because hot air rises above cold air. The air inside the balloon is heated above the temperature of the air outside the balloon. The warmer air trapped inside the balloon then causes the balloon to float above the outside colder air.
How do hot air balloons use air to fly?
Hot air balloons use the fact that hot air rises as a way to make balloons fly. When the air inside the balloon is heated, it rises, and this creates lift which is used to make the balloon fly.
What are the gases on a hot air balloon?
Hot air balloons are simply that, hot air. Air inside the balloon or envelope is heated, this becomes less dense than the surrounding air therefore creating buoyancy.
What makes balloons go up?
One of two reasons, either the gas inside the balloon is lighter than the air around it, as would be the case if the balloon was filled with helium, or the gas inside the balloon is hotter than the air around it, as is the case with hot air balloons.
Where do birthday balloons go when they are released in the air?
With helium filled balloons, they rise upwards as the gas inside is of a lower density than the atmosphere around them. The balloon will continue to rise and the gas inside it will expand as the atmospheric pressure decreases with increasing altitude. Eventually, the gas inside the balloon will expand enough to burst the balloon and the balloon will fall back to the ground. When and where this happens depends on weather conditions, air temperature, the rubber used in the balloon, etc.
Why are Hot air balloons are filled with air instead of helium?
They are not! The air inside them is trapped in the balloon and heated, expands, becomes less dense and rises therefore pulling the balloon up with it. If helium was used it would explode! :)

Why do hot air balloons travel upward?
The heated air causes the whole balloon to rise. When the air inside the balloon cools down, or when the hot air is let out, the balloon goes down.
Why do balloons expand by hot heat?
Answer:The air inside the balloon gets heated and expands as the air molecules move apart due to temperature.
Why do baloons float in air?
Balloons are full of a gas called 'helium', which is lighter than air. The helium is trapped inside the balloon, that's what makes it float.
What if a balloon is heated what happens to the volume of the air in the balloon if the pressure is constant?
For a balloon that is sealed and not full the volume of air inside the balloon will increase as it is heated. This is not however how hot air balloons work. A hot air balloon is essentially a fixed volume when it is inflated. If the air inside the balloon is heated the air inside becomes less dense so some of the air exits the balloon via the mouth of the balloon. As the air inside the balloon cools it becomes more dense so some air is ingested via the mouth of the balloon to keep it full. With each heating and cooling cycle, the pressure inside the balloon remains constant, the volume of the balloon remains constant but there is this movement of air out of and back into the balloon.

What does a balloon do when heated?
the heat makes the molecules inside the balloon travel faster, pushing outward on the balloon. This, the balloon expands when heated

Does a air in a balloon?
A balloon floats in the air when the molecules inside the balloon are less dense. The gas inside a helium balloon is in essence "lighter" than the air around it, causing a buoyancy effect which makes the balloon float. This can also be seen in hot air balloons when the air molecules are heated by the propane torch and excited, thus creating a less dense environment inside of the balloon compared to outside of the balloon.

Why doesn't an inflated balloon shrink when heated?
Because as the balloon is heated, the gases on the inside of the balloon begin to expand and press out on the walls of balloon. If a balloon is refridgerated, the opposite is true: the gases on the inside of the balloon will begin to contract, causing the balloon to shrink.
