Are all noble gases lighter 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.
What is used as lifting gas in balloons?
Hydrogen gas makes the ballon lighter than air therefore it drifts upwards
How many times heavier is helium than carbon?
Helium is a gas and is far more lighter than carbon which is a solid.
What percentage of hydrogen is lighter than air?
100% of hydrogen is lighter than air
Is Saturn lighter or heavier than water?
Saturn is much lighter than water. It is a gas giant made primarily of hydrogen and helium, with a density lower than that of water.
What is the difference between lighter than air and heavier than an air vehicle?
"Lighter than air" aircraft are lighter than air! The most common are blimps. They do not rely on wings to generate lift. They contain a lighter than air gas (ex:helium) that lifts the craft into the air when ties to the ground are released. "Heavier than air" aircraft are the opposite. They rely on wings to generate lift to get into the air. Common heavier than air aircraft are general airplanes you see in the sky everyday.
Is red hair lighter than blond?

Why is freon continuously used as coolant despite protests from environmentalists?
That's because most of the environmentalist wackos live in California, and they don't need air conditioning. I bet if they lived in Texas or Florida they would change their tune. The HFC refrigerants used today are much safer for the ozone than the older CFC's. Besides the only other alternatives to the common refrigerants we use today are chemicals like propane, and ammonia.
What is plastic pipe used for?
The most common use of plastic piping is in plumbing. It's lighter and cheaper than metal piping. Rubberized piping can be considered as garden hose piping.
What gas inside a normal balloon?
Helium is the most common gas used to inflate balloons because it is lighter than air. This allows the balloon to float and rise when filled with helium.
Can you use new freon in r22 systems?
no. it is not a good idea. new hfc refrigerants require a different type of oil than the R22 units. the new refrigerants typically run at higher pressures than the R22 units.
Are comets heavier or lighter than the moon?
I am pretty sure that comets are lighter than moons but it depends on the comet
