If I fill a balloon with helium it will float. Why does it float? Estimate the mass of helium in the balloon.

Sagot :

Answer:

It only makes objects float if they are less dense than their surroundings, like a boat on water, or a helium balloon in air. Buoyancy works due to displacement. ... In the case of a balloon, the helium inside the balloon weighs less than the same volume of air the balloon displaces

Explanation:

Answer:

In the case of a balloon, the helium inside the balloon weighs less than the same volume of air the balloon displaces. ... So a helium balloon has two opposing forces acting on it: gravity pulling it down, and buoyancy pushing it up. Buoyancy wins, so you can't really weigh a balloon, even though it does have weight.

Knowing the volume of air displaced by the helium balloon, we can calculate the maximum mass the balloon can lift. ... Helium, which has a mass of 4.00 g/mol, has a density of 0.164 g/l. Thus, a one-liter balloon of helium can lift a mass of (1.18-0.164) = 1.02 g.
