the heated air inside of the balloon has less density than the cold outside air so the hot air is more buoyant (e.g. the Bowling ball sinks but the beach ball floats because the density of the beach ball is less than the water)
Hot air is lighter than cold air, so cold air sinks and hot air rises; that makes the hot air balloon rise (if the air around the hot air balloon is heated as well, it won't rise, or sink if in the air).
The volume of air increases on its heating hence the balloon rises on heating
The hot pressure{air}builds up so the balloon goes up.
A hot air balloon is called an hot air balloon because, the inside is heated up to make it less dense, allowing it to rise. Meaning, your heating up the air inside the balloon, hence, the name: Hot air balloon.
When the gas (air) in a hot air balloon is heated it becomes less dense. This makes the balloon more buoyant so it rises.Because heating the air inside the balloon makes it less dense than the air surrounding the outside of the balloon, so it will rise.
Hot air is less dense compared to cold air. The heated air in the balloon will rise, making the balloon float in the air.to make it rise.

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.

When the air inside a hot air ballon is heated the hot air rises, which makes the ballon rise hope i helped ;)

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.
because the density in the balloon is heated so it rises higher than it being unheated
Heating causes the air inside the balloon to expand. Some of the warm air leaves through the bottom opening of the balloon, keeping the pressure constant.
to make a hot air balloon rise you use hot air
