Question

Constants Part C Hot air balloons float in the air because of the difference in density between cold and hot air. Consider a balloon in which the mass of the pilot basket together with the mass of the balloon fabric and other equipment is mb. The volume of the hot air inside the balloon is Vi and the volume of the basket, fabric, and other equipment is V2. The absolute temperature of the cold air outside the balloon is T and its density is pe. The absolute temperature of the hot air at the bottom of the balloon is Th (where Th>Te). The balloon is open at the bottom, so that the pressure inside and outside the balloon is the same here. Assume that we can treat air as an ideal gas. Use g for the magnitude of the acceleration due to gravity What is the magnitude of the buoyant force Fs on the balloon? Express your answer in terms of g, pe, Vi, and V2 View Available Hint(s) Submit
