aces 12,800 cu. ft. of air, the totalbuoyant force on it is equal to the weight of 12,800 cu. ft.of air. This is 12,800 X j- = 16,000 oz. = -l-\\^ = 1000 Ib.The balloon, then, could lift a total weight of 1000 Ib. Laws. We have now studied three different laws of natureapplying to gases, namely: —… … FIG. 39. Illustrating the buoyantforce of air. MECHANICS.
