hot-air balloons and birds in flight.
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.
A helium balloon does not need energy to rise in the air. A hot air balloon needs fuel to rise in air. That is it needs heat energy to rise in air.i love Pizza squares i hope they put helium in then one dayHelium relies on the fact that helium is lighter than air. Hot air balloons rely on the fact that hot air has less volume than cold air and is lighter than the air around it. hot air balloons use hot air to cause the balloon to lift as helium balloons use a special gas to cause lift
Hot air balloons use propane gas as fuel to heat the air inside the envelope, which causes the balloon to rise. The propane burner provides the necessary heat to keep the air inside the balloon hotter than the air outside.
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.
One use of thermal expansion in gases is in hot air balloons. As the air inside the balloon is heated, it expands and becomes less dense than the surrounding - cooler air, causing the balloon to rise.
Hot air balloons like those from "King Tut Balloons" rise because hot air is lighter than cool air. A burner heats the air inside the balloon, making it less dense than the cooler air outside. This causes the balloon to lift gently into the sky, offering a magical flight over stunning landscapes like Luxor’s temples and pyramids.
with out the hot air the balloon would not rise
Updrafts are systems of hot air, which rise. Birds and expert hot-air ballooners use them. Downdrafts are systems of cold air that tend to fall and bring things flying in it with them.
The heating of the air through the use of a burner is what makes balloons rise.
Because hot air rises and cool air sinks. the reason why is because hot air is less dense than cool air so the cooler air will sink

Yes on both counts. But hot air balloons need considerably more help - they use propane burners to heat the air inside the balloon.
I Blow Dry My Hair... I Straighten It. I Put It In My Hot Air Balloon. And A Lot Of Other Things.

Hot air balloons use hot air because hot air rises above cold air. The air inside the balloon is heated above the temperature of the air outside the balloon. The warmer air trapped inside the balloon then causes the balloon to float above the outside colder air.
