A hot-air balloon achieves its buoyant lift by heating the airinside the balloon, which makes it less dense than the air outside.Suppose the volume of a balloon is 1800 m3 and therequired lift is 2700 N (rough estimate of the weight of theequiptment and passenger). Calculate the temperature of the airinside the balloon which will produce the required lift. Assumethat the outside air temperature is 0 degrees C and that the air isan ideal gas under these conditions.How do I go about applying the ideal gas law to a problem like thiswhich asks me to factor in buoyant lift?Thanks!
