Hot air has less density than air at ambient temperature. And just like with water, something that is lighter than the media that surrounds it will try to float to the top.

Why does a balloon need hot air?
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.
How does convection work in a hot air balloon?
When the air inside a hot air ballon is heated the hot air rises, which makes the ballon rise hope i helped ;)
Why do helium and hot air balloon's rise?
Because helium is less dense than air, so it rises. Hot air balloons rise because heated air from the burner becomes less dense and therefore rises.
Why would heating the gas in air balloon make balloon 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.
What is a example of convection?
hot air ballon because since the air is heated in the hot air balloon it will rise, And water boiling in a pan if you were cooking pasta you can see the pasta rise and fall with the convection current in the boiling water

Why does heating the air in hot air balloon make it rise?
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 air in hot air balloon is heated to make the balloon rise?
The volume of air increases on its heating hence the balloon rises on heating
Why does a hot air balloon rise when the air inside it is heated up?
The hot pressure{air}builds up so the balloon goes up.
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 did they call it the hot air balloon?
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.

Why would heating the gas in a hot air balloon make the balloon rise?
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.
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.
Why do hot air balloon rise up?
because the density in the balloon is heated so it rises higher than it being unheated
Why does a hot air balloon rise when the air inside it is heated?
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.
Why does a hot air balloon rise when the air inside is still heated?
Because hot air rises, so if there is hot air inside the baloon, the balloon will be compelled to ride because the air pushes against the balloon upward, and, long story short, the air wins. Hope this helped.
