How does convection explain the ability to fly hot air balloons?
Convection explains the ability to fly hot air balloons because hot air rises due to its lower density compared to cooler air. As the air inside the balloon heats up, it becomes less dense and creates buoyancy, lifting the balloon. This convection process allows the balloon to float in the cooler air above.
Is helium used in hot air balloons?
No, it is not. "Regular" air is used, and it is heated. Hot air is less dense than cooler air, and it will rise. If hot air is trapped in an envelope, it will give lift to the envelope and an attached payload.
Which gas do you use for hot air balloons?
Hot air balloons typically use propane gas as a fuel source for the burner that heats the air inside the balloon envelope. The propane is burned to heat the air, which causes the balloon to rise.
Does a hot air balloon have helium inside it?
Hot air balloons do not use helium; they are typically filled with hot air. Helium is non-flammable and more commonly used in other types of balloons like weather balloons or party balloons. The hot air inside a hot air balloon is what allows it to rise and float.
What gas do hot air balloons contain?
Hot air balloons are typically filled with heated air, which is lighter than the surrounding air and provides lift. Some balloons may also use helium or hydrogen gas for buoyancy, but hot air is the most commonly used lifting gas for traditional hot air balloons.
What are hot air balloons used for now a days?
Hot air balloons are now mostly used for leisure

What is the function of hot air in science?
In science, hot air is often used in experiments to demonstrate principles of thermodynamics, such as convection and expansion. Hot air can be used to generate movement in systems, such as hot air balloons, and to study how heat affects matter. Additionally, hot air can be used in industrial processes like drying or heating.
How were hot air balloons used by the military?
The first use of hot air balloons was in the American Civil War for surveillance of troop movements.

Why is hydrogen used to inflate hot air balloons?
Hydrogen is not used to inflate hot air balloons. Just regular air is used which is then heated to make the balloon more buoyant as hot air weighs less than cold air. Hence the name hot air balloons.
How were hot air balloons used during World War 1?
Hot air balloons were used to spy on the enemy. They were also used to communicate, send supplies, and drop bombs.
What source is used to fly hot air balloons?
Wind !... The balloons are filled with hot air, which causes them to rise. They are then at the mercy f the wind direction.
Is a hot air balloon filled with helium?
No, hot air balloons are typically filled with hot air to become buoyant and rise. Helium is an alternative gas used in some balloons, like party balloons or weather balloons, due to its lighter weight than air.
Why do we use warm air in a hot air balloons?
Warm air is used in hot air balloons because it is lighter than cool air, providing the necessary lift for the balloon to rise. As the air inside the balloon gets heated, it expands and becomes less dense than the surrounding air, causing the balloon to float.
