why a hot air ballon goes high up in the sky

Answers

Answered by brainlygirl2

Answer:

Hot air balloons rise because the heated air is less dense and therefore lighter than the surrounding air. But hot air balloons need oxygen for their burners to work – and the higher they rise, the thinner the air and the less oxygen available.
