Yes. Slightly.
**********2nd Opinion***********
Carbon dioxide has a higher density than air.
Air density is about 1.3 g/L
CO2 density is about 2 g/L
Nitrous Oxide is heavier than air.
Some are heavier, but some are lighter. For example, methane rises but propane sinks.
Dry air is heavier than wet air because water vapor is less dense than the other components of dry air, such as nitrogen and oxygen. When moisture is added to the air, it displaces some of the heavier components, making wet air less dense and therefore lighter.
hydrogen
No. Helium is lighter than air
Yes solvents are heavier than air
Nitrous Oxide is heavier than air.
Yes, argon is heavier than air. Argon has a higher density than air, so it will sink below the air in the atmosphere.
"Heavier than air" refers to airplanes.
An airplane is a heavier than air flying craft
Yes, LP gas is heavier than air.
Gas is heavier than oxygen. Cold air is heavir than hot air
One is lighter and the other one is heavier. :D
they are heavier than air hence why they don't fly unless in motion.
An airplane is a heavier than air flying craft
Yes, LP (liquefied petroleum gas) is heavier than air.
Just, simply, Lighter than Air Vehicles are lighter than air, so that makes them fly, and Heavier than air vehicles are heavier than air, but they use airfoils on the wings to fly.
