Some are heavier, but some are lighter. For example, methane rises but propane sinks.
Carbon dioxide gas is slightly heavier than air.
Many hydrocarbons have a lower density than air but not all.
they're lighter than air
Yes solvents are heavier than air
No, water is heavier than air.
Nitrous Oxide is heavier than air.
Moist air weighs less than dry air at the same temperature. This is because the density of diatomic Oxygen and Nitrogen is greater than water vapor (H2O).
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
Yes CFC's are much heavier than air. If you filled a balloon with CFC's, it would drop, not float away.
Gasoline is a mixture of various hydrocarbons, most of which produce vapors that are denser than air.
Yes solvents are heavier than air
No, water is heavier than air.
Yes, it is heavier than air.
Is natural gas heavier than air
"Heavier than air" refers to airplanes.
An airplane is a heavier than air flying craft
Nitrous Oxide is heavier than air.
Yes,it is heavier than air.It sinks to bottom in air.
Gas is heavier than oxygen. Cold air is heavir than hot air
One is lighter and the other one is heavier. :D
Moist air is heavier than dry air, because of the water.
