balloon
Helium is lighter (less dense) than oxygen & nitrogen.
The density of helium is less than that of air. Due to this reason, balloons filled with helium will float in air.
Helium has a lower density than air.
They are both very large low-density planets composed mostly of volatile materials. Jupiter is mostly hydrogen and helium while Uranus is mostly water, ammonia, and methane on the inside.
They are Hydrogen, Helium, methane and ammonia.
helium
NaCl!
If the question is regarding helium's density, helium has a very low density as its natural state is as a gas. It's density is 0.0001785 grams per cubic centimeter.
Helium and somthing else that i forgot the name XD sowy im only 3
Helium is lighter (less dense) than oxygen & nitrogen.
Its atmosphere is.
Helium
The density of helium is less than that of air. Due to this reason, balloons filled with helium will float in air.
The density will be 50 % from the initial value.
Cristalized Ammonia
hydrogen, methane, helium, ammonia
Helium's density is less than the density of air, so it floats in air.
