Why do balloons float when you put helium in them?
The helium weighs less than air- so when the balloon is filled, it displaces the heavier air, and floats. Just as a bit of wood weighs less than water, and floats on water. In a vacuum, a helium filled balloon would not float (but it may pop)
Is helium is filled in balloons?
because helium weighs 4u and air (80% nitrogen) weighs about 14u. because helium has less mass, it has less gravity and rises. it has also to be a gas as a substance in a gas form has a much lower density as a liquid or solid form. earlier they used hydrogen (1u), but that is highly explosive. (u is relative mass for atoms)
What weighs more 2 pounds or 30 ounces?
32 ounces
A package that weighs one pound and five ounces weighs how many ounces?
1 lb + 5 oz = 16 oz + 5 oz = 21 ounces
How many kgs is equivalent to 5 ounces?
On earth, an object that weighs 5 ounces has a mass of 0.1417 kg. On the moon, an object that weighs 5 ounces has a mass of 0.8682 kg.
If 87 balloons weighs 227 grams how much does one balloon weigh?
2.6091954023 grams
Does air resistance keep a hot air balloon in the air?
No, hot air balloons are kept up in the air by buoyancy, the same thing that keeps helium balloons up in the air, or that keeps ships afloat. The hot air in the balloon is less dense than the surrounding air, so the balloon weighs less than the air it displaces, at least while the balloon is rising.

Why is hydrogen used to inflate hot air balloons?
Hydrogen is not used to inflate hot air balloons. Just regular air is used which is then heated to make the balloon more buoyant as hot air weighs less than cold air. Hence the name hot air balloons.
Why don't normal balloons stay in the sky?
Due to the weight of the balloon. A balloon is merely a capsule full of air so it will fall to the ground as the balloon weighs it down. A helium balloon will rise into the air because helium is less dense than normal air (i.e. it weighs less). The air inside the balloon is the same density as the air outside. The balloon material itself is heavier than air, which causes the balloon to sink. If you decrease the density of the trapped air, such as by heating it or replacing it with hydrogen or helium, the balloon may become even lighter than the balloon material and an equal volume of normal air, in which case the balloon will float or rise.
How does Jacques Charles law relate to aerodynamics?
He 'flew' in helium balloons. Volume increases as temperature increases. In a hot air balloon temp increases so volume increases and some air must leave the balloon. The balloon now has lift because it weighs less than the cold air outside the balloon, just like buoyancy of a boat in water.
How balloons and blimps are able to fly in oceans of air?
Balloons float because of the same principal as how ships float: bouyancy. A ship displaces a volume of water. If the ship's weight is less than the volume of water that it displaces, then it will float. Same is true for a balloon. It displaces a volume of air. If the Hydrogen or Helium in the balloon weighs less than the volume of air it displaces, then it will rise.
How does a hot air balloon work?
Hot air balloons get their buoyancy from hot air created by a propane burner at the base of the balloon. Hot air is less dense than cold air and so weighs less. When the cold air that is displaced weighs more than the balloon, the balloon will rise. The balloons weight is controlled by turning the burner on and off when needed. The hot air is less dense than the outside air and so the balloon is squeezed upwards by the surrounding air. The air becomes less dense as more heat is applied, particles separate more and more when heat is applied. The more heat is applied the further apart and less dense the particles become.
Just say you had a bunch of party balloons filled with helium tied to a person how many balloons would it take for a 150lb person to jump like they were on the moon?
well it depends how much the person weighs so do this take the persons weight and multiply it by five the divide it by how many inches the balloon is around then last but not least you add how much time it takes to blow up the balloon (this is because different heilium machines have different presure gages) and there is how many balloons it takes to lift a person off the ground wit regular party balloons
If a seashell weighs 18 ounces and a rock weighs 1 pound which weighs more?
The seashell. The rock only weighs 16 ounces.
A penny weighs how many ounces?
It only weighs 2.5 grams, which is 0.088 ounces.
Why does hot air balloons float?
To put it simply, hot air balloons rise due to heat produced by the burning of propane, the heat travels up through the balloon's valve into the balloon itself (the envelope) and up to the parachute valve. Since heat rises, the hot air balloon its self rises. Better answer: a boat floats on water because it weighs less than the water it replaces. likewise, a hot air balloon floats, because the weight of the total balloon + hot air is less then the volume of cold air it replaces. Air has a weight too, but normally you don't notice.
