Question

Why do hot air balloons fly high?

Answer

Helium balloons rise higher than hot air balloons. Hot air balloons rise because the heated air is less dense and therefore lighter than the surrounding air.

As a helium balloon gains altitude, the helium inside expands and becomes less dense, thus enabling the balloon to continue rising.
