No. Carbon dioxide is heavier than helium.
Helium, because it is lighter than air.
This is because helium is much lighter than our atmosphere of oxygen, nitrogen and other gases so it floats.
Helium is a gas and is far more lighter than carbon which is a solid.
A helium-4 atom is just about 1/3 the mass of a carbon-12 atom.
Helium has a mass less than that of carbon dioxide.so it will help the ship to float over the water.more over it will not react with any object as it is a noble gas.
Because, carbon dioxide is heavier than air whereas helium is lighter than air.
Helium, because it is lighter than air.
The composition of Earth's atmosphere is mostly nitrogen, carbon dioxide, and oxygen. All of these elements are denser than helium, and therefore it tends to rise.
This is because helium is much lighter than our atmosphere of oxygen, nitrogen and other gases so it floats.
carbon dioxide is heavier than oxygen therefore oxygen is lighter.
Helium(0.1786 g/L) is lighter than air(1.2 kg/m3) due to physical property density.Density of air is more than helium due to presence of many gase like oxygen carbon dioxide etc.
Helium is a gas and is far more lighter than carbon which is a solid.
People generally use helium in balloons because helium is lighter than the air in our atmosphere (mostly carbon dioxide and oxygen), so it floats. As opposed to filling it with oxygen or carbon dioxide, where it would just sink to the ground because it has the same weight as the air it is in.
Helium is a relatively light gas which is lighter than air at ground level. Exhaled air contains a lot of water vapour and carbon dioxide relative to normal air. Since ground level air is less dense than helium, adding water vapour and carbon dioxide makes exhaled air even more heavier than helium.
The gas commonly used in balloons is helium. It is lighter than air, which causes the balloon to float when it is filled with helium.
Carbon dioxide will keep a balloon inflated longer than helium will, because its molecules are much larger and therefore less able to escape through the material of which the balloon is made.On the other hand, helium is much lighter so will give a balloon greater lift while it lasts.
In fact there are seven elements lighter than oxygen: hydrogen, helium, lithium, beryllium, boron, carbon and nitrogen.
