Instead of blowing normal air (your breath, a pump, etc.) into the balloon, you'd use helium to make it float.

Why does a balloon need hot air?
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.
Why would a hot air balloon pilot heat the air in the balloon to make it rise?
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.
How do you make air lighter so that it will cause a balloon to rise?
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.
What gas makes a balloon rise into the air?
Helium. It is lighter than air and provides buoyancy, causing the balloon to rise.
Why would heating the gas in air balloon make balloon 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.
What chemicals from the periodic table make a hot air balloon rise?
There are many chemicals found in a hot air balloon to make it rise. The main elements/chemicals are Helium and Hydrogen.
Why can air balloon rise to the sky?
it can rise because of the helium and the gases help make it rise to the sky
How do you make a balloon rise into the air?
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.
How is a hot balloon lifted into the air?
to make a hot air balloon rise you use hot air
What would heating the gas in an air balloon make the balloon rise?
Simple...hot air rises..
Would a hot air balloon pilot heat or cool the air in the balloon to make it rise?
He would heat it.
Why does a balloon need hot air?
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.
Why would a hot air balloon pilot heat the air in the balloon to make it rise?
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.
Will increasing the temperature in a hot air balloon make it rise faster?
Yes.
How do convection currents make a hot air balloon to rise?
because the air becomes less dense and spreads out so becomes hotter and hot air rise so the balloon does.
How does helium make a balloon rise when air doesn'?
Helium is lighter than air. So helium balloon rises in air.
Why did they call it the hot air balloon?
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.
