Why does a hot air balloon need flame in order to take off?
A hot air balloon needs a flame to heat the air inside the balloon, making it less dense than the surrounding air. This temperature difference creates lift, allowing the balloon to float upwards. Without the flame, the air inside the balloon would cool down and the balloon would descend.
What happens to a hot air balloon when the burner is turned off?
When the burner is turned off, the air inside the hot air balloon starts to cool down. As the air cools, the balloon loses lift and begins to slowly descend back to the ground. Without the burner heating the air inside the balloon, it will eventually land.
What happens to a balloon after a cool change?
The drop in temperature will cause the atoms (or air) inside the balloon to fall in energy levels, this will result in the pressure inside the balloon dropping, and may cause the balloon to loose its shape.
How does a balloon pilot control BOTH acsent and descent of a balloon?
A balloon pilot controls ascent by heating the air inside the balloon with a burner and descent by allowing the air to cool or venting it.
How does heat make a hot air balloon go up?
When the air inside the balloon is heated, it becomes less dense and lighter than the surrounding cool air. This causes the balloon to rise as it floats upwards since the hotter air inside is less dense and buoyant than the cooler air outside the balloon.
When the balloon is up in the air the burner is turned off and the balloon drifts along with the wind What will eventually happen to the air inside the balloon?
As the balloon cools down, the air inside will also cool. This will cause the air pressure inside the balloon to decrease, potentially leading to the balloon descending back to the ground due to the decreased pressure.

What are some cool things to do for a science fair?
Some cool experiments like k +H2O, bringing a balloon full of h2 near a flame, etc.

A balloon pilot controls ascent by heating the air inside the balloon with a burner and descent by allowing the air to cool or venting it.
When the balloon is floating high above the ground how could the balloonist make the balloon descend gradually?
To make the balloon descend gradually, the balloonist can release some hot air from the envelope by opening the top valve. This will allow the balloon to cool down slightly and start descending. Adjusting the burner flame to produce less heat can also help with a gradual descent.
How come when you put water in a balloon and you put it on top of lit candle it won't pop?
When you put water in a balloon and place it over a lit candle, the water in the balloon absorbs and distributes the heat from the flame, preventing the balloon from bursting. The water acts as a heat sink, keeping the balloon cool enough to withstand the heat from the candle without melting or bursting.
What will happen if you inflate a balloon with warm air and take it to a cold place?
The air inside cools. Cool air shrinks. The balloon gets smaller.
What happens when you leave a balloon in the freezer?
When you leave a balloon in the freezer, the air inside it will cool and contract, causing the balloon to shrink in size. This happens because the volume of gases decreases when they are cooled, causing the balloon to deflate.
What is the role played by the gas contained inside a hot air balloon?
The gas (hot air) in a hot air balloon gives the ballon its "lift". In nature, hot air rises. This is why it is usually cooler near the floor of your house that near the ceiling. Filling a balloon with warm air and then heating it with a flame gives the balloon more and more lift. By controlling the amount of heat applied to the gas inside the balloon, balloonists can control how high they can fly. Heat things up and you go higher...let it cool down (slowly) and you will land safely.
How does heat make a hot air balloon go up?
When the air inside the balloon is heated, it becomes less dense and lighter than the surrounding cool air. This causes the balloon to rise as it floats upwards since the hotter air inside is less dense and buoyant than the cooler air outside the balloon.
