A balloon needs hot air to make it rise because hot air is less dense than cold air. When the air inside the balloon is heated, it becomes lighter and causes the balloon to lift off the ground and float in the air.
Heating the air in the balloon makes it less dense than the surrounding air, causing the balloon to become buoyant and rise. As the air inside the balloon cools, it becomes denser and the balloon descends. This process allows the pilot to control the altitude of the balloon.
To make air lighter, you can heat it up. Hot air is less dense than cold air, so it rises. When you heat the air inside a balloon, it becomes lighter than the surrounding air and causes the balloon to float upward.
Helium. It is lighter than air and provides buoyancy, causing the balloon to rise.
Heating the gas inside the balloon causes it to expand and become less dense than the surrounding air. This creates a buoyant force greater than the weight of the balloon and its contents, causing the balloon to rise.
There are many chemicals found in a hot air balloon to make it rise. The main elements/chemicals are Helium and Hydrogen.
it can rise because of the helium and the gases help make it rise to the sky
To make a balloon rise in the air, one way is to fill it with a lighter-than-air gas, such as helium or hydrogen. The gas inside the balloon is less dense than the surrounding air, enabling it to float and rise. The amount of gas and the size of the balloon will determine how high it can rise.
to make a hot air balloon rise you use hot air
Simple...hot air rises..
He would heat it.

Yes.
because the air becomes less dense and spreads out so becomes hotter and hot air rise so the balloon does.
Helium is lighter than air. So helium balloon rises in air.
The name "hot air balloon" comes from the fact that hot air is used to make the balloon rise. The balloon is inflated with heated air, which is less dense than the cool air surrounding it, causing the balloon to lift off the ground.
