Even those massive balloons that can weigh hundreds of pounds float because of the buoyancy force within them ... b1 architekci WebApr 6, 2024 · It’s responding to the air around it. Helium floats because it is buoyant; its molecules are lighter than the nitrogen and oxygen molecules of our atmosphere and so they rise above it. And now the balloon rises “upward” toward the thinner air like a diver coming up from deep water. WebAdd the weight of the three empty balloons and their ribbons to get the buoyancy. For example, say the weight of the spoon is 20 g, the weight of the spoon with the balloons and ribbons attached is 15 g, and the weight of the balloons and ribbons is 3 g. Then the total lift supplied by the helium gas equals 20 - 15 + 3 = 8 g. See Equation 1. b1 archive WebApr 22, 2012 · Helium balloons float because the helium gas is less dense than regular air.
