How do companies get hold on helium?
Because helium is only about 0.0005% of air ... not enough to make recovery economically feasible.
What is the percent of helium in the air?
Helium comprises only the tiniest portion of the earth's atmosphere. It represents only about 5.24 parts per million by volume, which is about 0.000524% of the atmosphere. Use the link below to the Wikipedia post on what's in Earth's atmosphere. You might be surprised!
How deep can a person dive with helium-oxygen air tanks?
It depends on the percentage of the mixture You can adjust the percentage depending on desired depth and length of dive.
Why does a helium balloom float in air?
Helium is lighter than air. so balloons filled with helium will float in air
How does helium make a balloon rise when air doesn'?
Helium is lighter than air. So helium balloon rises in air.
Helium hydrogen and air are in this state of matter?
Helium, hydrogen, and air are gases.
Is air heavy than helium?
Yes. air is heavier than helium.
What is helium gas or air?
helium is a gas. air is a bunch of different gasses.
Why does a helium ballooon float in air?
Helium has a lower density than air.
Why does a helium balloon float in the air rathen than sink?
because helium is ligter than air
What has more density air or helium?
The density of helium is less than the density of air. You can infer this without doing any calculations by thinking about the classic example of inhaling the helium from a balloon and talking. Your voice gets squeeky high because helium is less dense than air - that is, your sound waves propagate faster through helium than through air, therefore helium is less dense.
What are helium's practical uses?
Helium is lighter than air. So balloons or air ships filled with helium will float.
