What do they fill hot air balloons with?
Hot air balloons are filled with heated air, usually generated by a gas burner that heats up the air inside the balloon envelope. This hot air makes the balloon buoyant and allows it to rise in the sky.
Why does a hot air balloon only go up when it is hot air?
Hot air is less dense then the surrounding air, meaning it's lighter then regular air, allowing it to naturally lift. If something catches that lifting air, and the air is so light that it can lift the required weight up, then it will lift. That's why a hot air balloon requires hot air to lift.
Why is nylon suitable for an hot air balloon?
It is heat resistant, light, and resists tearing
How do hot air balloons stay in air?
hot air rises
Where in the atmosphere do hot air balloons float?

Why lighter than air balloons fly?
air balloons or hot air balloons fly because they fill with a very light type of air. The air is hot air.
What is the cause for the flickering of objects when seen through hot air?
The speed of light changes if the density of medium changes. In hot air, the density is less so due to the change in speed of light, we think that it is flickering.
In the atmosphere a hot air layer is found above a cold air layer How is the separation achieved and why does hot air always tend to rise?
It is because a hot air is a light matter while a cold air is a heavy matter of gas. Like, the difference of low(hot) pressure and high(cold) pressure area.
Why are Ventilators are kept at the top of a room?

Why are air conditioners placed at the top?
Air conditioners are placed at the top as hot air is light it rises up. So air conditioners are placed at the top to help cool the hot air. For example: The hot air which is up becomes cool as you switch on your air conditioner. Then the cold air is heavy so it comes down and then again the hot air goes up and the same process is carried throughout.

How do you prove that hot air rises?
Hot air is less dense (lighter) than colder air, so warmer air will naturally rise above the cooler air.
