A hot air balloon achieves itsbuoyant lift by heating the airinside the balloon, which makes itless dense than the airoutside.
Suppose thevolume of a balloon is 1800m3 and the requiredlift is2700N. Calculate the temperature of the air insidethe balloon whichwill produce the required lift. Assume thatthe outside airtemperature is 0*C and that air is an ideal gasunder theseconditions. What factors limit the maximumaltitude attainable bythis method for a given load? (Neglectvariables like wind.)
