Add 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.

F B = w fl, where F B is the buoyant force and w fl is the weight of the fluid displaced by the object. This principle is named after the Greek mathematician and inventor Archimedes (ca. 287–212 BCE), who stated this principle long before concepts of force were well established. Figure 14.21 (a) An object submerged in a fluid experiences a ...

Q: Why do helium balloons float in the air? A: Helium balloons float because helium gas is less dense than the surrounding air. This makes the balloon positively buoyant, causing it to rise. Q: Does the shape of an object affect its buoyancy? A: Yes, the shape of an object can influence its buoyancy.

The helium balloon displaces an amount of air (just like the empty bottle displaces an amount of water). As long as the weight of the helium plus the balloon fabric is lighter than the air it displaces, the balloon will float in the air. It turns out that helium is a lot lighter than air. Though the difference is not as great as that between

When it comes to inflating balloons, helium is the gas of choice for two primary reasons: Safety: ... Lighter than Air: Helium is approximately one-seventh the density of air, making it ideal for flotation. However, it's worth noting that helium is a limited resource, spurring ongoing research into sustainable alternatives.
