HYDROGN IS 14 TIMES LIGHTER THAN AIR.
It will go up. Hydrogen is lighter than air
beecause hydrogen is less dense and light then air , easy to fly..the hydrogen in the balloon is lighter than the air outside of it.density of hydrogen is lower than air
something that is lighter than the molecular mass of water.Mr of water= 2(1)+16=18therefore, anything with a Mr of lesser than 18 will be lighter than water vapour.example: hydrogen gas.Mr of hydrogen gas= 2(1)= 2therefore, it is lighter than water vapour.
Xenon is more than 4.5 times heavier than air.
There are many, but one is Helium
Hydrogen is lighter than Helium.
100% of hydrogen is lighter than air
No, helium is almost 4 times as heavy as hydrogen.
The mass of an electron is approximately 1⁄1836 of a proton. Thus as hydrogen is made of one proton and one electron, hydrogen is 1837 times heavier than an electron.
molecule is lighter than hydrogen.....................
Hydrogen and Helium are both lighter than air.
hydrogen
hydrogen
this happens because hydrogen is lighter than air
because hydrogen is collected by the upward displacement of air although it is 14.5 times lighter than air B)
