Question

THE GROWING BALLOON Add ем Very large air bags are used for high- altitude weather balloons. At ground level the bag is only partly filled with helium, just buoyant enough to rise. As the balloon rises, the less dense surrounding air allows the helium gas to gradually expand and the balloon grows larger. As it grows larger and larger, the buoyanty of the balloon a) increases b) decreases c) stays the same Save

Answer 1

is We know Bougant force depends upon volume. That why when volume expands, Its Bouyancy increases. Bouyancy Force = Density gravity & volume.
