No, helium has weight, but it rises when its in an expandable container such as a balloon because it is lighter than the nitrogen rich atmosphere but inside of a rigid container the helium can only add weight. (see the mythbuster's episode about the helium football)
What else can I help you with?
Is helium lighter or heavier?
Helium is lighter than air
Is helium lighter than earth?
yes. helium is lighter than earth or even air.
Which is lighter - helium or hydrogen?
Helium is lighter than hydrogen. Helium has an atomic number of 2, which means it has two protons and two neutrons in its nucleus, making it lighter than hydrogen, which has only one proton in its nucleus.
How much lighter is hydrogen compared to helium?
Hydrogen is about 7 lighter than helium.
What is lighter than argon?
helium
What is helium and What is its use for?
its the 2nd element on the periodic table and it makes things lighter, such as helium balloons, which float as helium is lighter than air
Will helium float in water?
Yes, helium will float in water. Helium is lighter than air, so it will also be lighter than water and rise to the surface when submerged in water.
If Air helium in balloons oxygen in a tank it is called?
If air is helium in balloons and oxygen is in a tank, it can be referred to as a gas mixture. Helium-filled balloons typically contain helium gas, which is lighter than air, allowing them to float. In contrast, oxygen in a tank is stored as a compressed gas, often used for medical or industrial purposes. Both helium and oxygen are important gases with distinct properties and applications.
Which gas is lighter than helium?
hydrogen
Is Helium lighter than smoke?
Yes
Is a helium balloon heavier than air filled balloon?
No. Helium is lighter than air
When balloons are filled with this they are lighter than air?
Hot air, hydrogen or helium are lighter than cold air.
