A hot-air balloon achieves its buoyant lift by heating theairinside the balloon, which makes it less dense than the airoutside.Suppose the volume of a balloon is 1600 m3 andthe required lift is2200 N (rough estimate of the weightof theequipment and passenger). Calculate the temperature of theairinside the balloon which will produce the required lift. Assumethatthe outside air temperature is 0°C and that air is anideal gasunder these conditions.
1°C
What factors limit the maximum altitude attainable by thismethodfor a given load? (Neglect variables like wind.)
