No it doesn't. You'd however need a larger volume of helium to weigh the same when heated. In other words, the density of the gas decreases when you heat it. The mass per unit amount (in moles or any other suitable unit) is always a constant.

Would a bottle of helium gas weigh more or less than an identical bottle filled with air at the same pressure?
No it would be lighter Imagine a 2 party balloons, one filled with helium and one jUst blown up Which one weighs less?
What is the mass of 18.8 moles of helium atoms?
1 mole of helium weighs 4.0026 g So. 18.8 of helium will weigh 75.25 g
What is the mass of 18.8 moles of helium (He) atoms?
1 mole of helium weighs 4.0026 g So. 18.8 of helium will weigh 75.25 g
Is Density of helium balloon is greater or less than air?
The density of helium is less than that of air. Due to this reason, balloons filled with helium will float in air.
Gas that is less dense than air?
Helium is a gas that is less dense than air. This is why a balloon filled with helium rises when released.
Do helium foot balls weigh less than regular foot balls?
no helium footballs are made for cheaters therefore they weigh less
Why do helium and hot air balloon's rise?
Because helium is less dense than air, so it rises. Hot air balloons rise because heated air from the burner becomes less dense and therefore rises.
Would helium weigh less than a bottle with no air?
Yes, because the helium is buoyant relative to the atmosphere at ground level. However, the helium would have more mass than the bottle with no air.
How much does 355 cubic liters weigh?
The answer depends on what you are weighing. Helium weighs less than water if the volume is constant.
Why are Hot air balloons are filled with air instead of helium?
They are not! The air inside them is trapped in the balloon and heated, expands, becomes less dense and rises therefore pulling the balloon up with it. If helium was used it would explode! :)
Why does putting a balloon filled with helium into an empty 10 pound barrel make it weigh less?
Helium has a lower density than air, therefore replacing the air in the barrel with helium decreases the mass of the barrel system thus the weight is decreased.
How does the average kinetic energy of the helium atoms in a balloon change as the helium gas is heated?
the theaory of gravity when lifted by a hot air substance is qiute simple if you think about it
How much does helium weigh?
The density of helium is approx. 0,9 g/L.
Would a bottle of helium gas weigh more or less than an identical bottle filled with air at the same pressure?
No it would be lighter Imagine a 2 party balloons, one filled with helium and one jUst blown up Which one weighs less?
Is hot air balloons filled with helium?
No, it is filled with heated air.
How much does a blimp weigh?
An empty blimp can weigh as much as 12,840 pounds. This is without being filled with helium. When full of helium the blimp may only weigh as much as 200 pounds.
Which gases weigh more than air Im aware that helium qualifies but also you are aware that you have few known sources of this gas IE What other gasses are a viable choice for diving?
- Helium is less dense than air. - For diving, as diluents for oxygen nitrogen and helium are used.
