1) A hot air balloon stays on the ground (or descends) when the air inside it is too cool. In this case, the weight of the balloon (blue arrow) is greater than the lift (red arrow). 2) When the air inside is a bit hotter, the balloon floats at a steady height because the lift force and weight are now the same.
Which is lighter a hot air balloon or a cool air balloon?
Hot air balloons are based on a very basic scientific principle: warmer air rises in cooler air. Essentially, hot air is lighter than cool air, because it has less mass per unit of volume. A cubic foot of air weighs roughly 28 grams (about an ounce). If you heat that air by 100 degrees F, it weighs about 7 grams less.
How big does a hot air balloon need to be?
If you heat that air by 100 degrees F, it weighs about 7 grams less. Therefore, each cubic foot of air contained in a hot air balloon can lift about 7 grams. That’s not much, and this is why hot air balloons are so huge — to lift 1,000 pounds, you need about 65,000 cubic feet of hot air.
