Why does a hot air balloon rise?

Biology
1 answer:
alina1380 [7]4 years ago
5 0

Answer: Hot air is less dense than cool air; the heated air causes the balloon to rise simply because it is lighter than an equal volume of cold air. Buoyancy is an upward force that the air exerts, and it helps hot-air balloons and blimps stay in the air. A hot air balloon uses a burner to heat up the air inside the balloon.

Hope this helps!!! Good luck!!! ;)

Why do classification systems change over time?
frutty [35]
<span>Classification systems change over time for a variety of reasons, but the basic gist of the matter is that as we learn more about the natural world around us, these systems change to fit in with and around the new information. Whilst it is worth learning the current system of classification, it is also important to remember that this could always change at any time.</span>
