No Argon is not lighter than air. Argon is 25% more dense than air.
Yes, it is heavier than air.
Natural gas is lighter than air and rises.
HYDROGN IS 14 TIMES LIGHTER THAN AIR.
Because it is heavier than air.
There is probally about 0.067% argon in the air
helium
Yes, it is.
argon is a component of "air" and as such air cannot be lighter than air, only more or less dense, however, judging from atomic masses, yes argon is heavier than nitrogen, oxygen, helium, and hydrogen, but depending on pollutants and other gases (CFC's, HCFC's, etc.) the compound that is air can vary slightly in mass.
Argon is 1.4 times heavier than air.
No. The molar mass of dry air is 28.97 g/mol. Noble gases are monatomic, so their atomic mass represent their molar mass. From this we can tell that helium and neon are less dense (lighter) than air, while argon (atomic mass 39.9) onwards are denser than air.
Argon is a little less than 1% of the air.
The balloon is lighter than air.
"Gas" could mean anything - there are many different types of gases. Some are lighter than air (composite of mostly nitrogen and oxygen) like methane or helium and some are heavier like argon or carbon dioxide.
100% of hydrogen is lighter than air
Yes methane is lighter than air because it is less dense than air.
Yes, it is heavier than air.
Hot air, hydrogen or helium are lighter than cold air.
