∙ 15y agoWe assume you mean methanol vapor? No, it is heavier than air. Methanol vapor can collect in low pockets and pose a fire or inhalation hazard.
Wiki User
∙ 14y agoYes methane is lighter than air because it is less dense than air.

Are hydrocarbons heavier than air?
Some are heavier, but some are lighter. For example, methane rises but propane sinks.
Is breath heavier than air?
No, water is heavier than air.
Is Nitrous Oxide lighter or heavier than air?
Nitrous Oxide is heavier than air.
Out of dry and wet air which is heavier?
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).
Is carbondioxide heavier than air?
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
Are hydrocarbons heavier than air?
Some are heavier, but some are lighter. For example, methane rises but propane sinks.
Will methane gas rise when released in the air?
Methane gas settles down because methane gas is heavier than and is carried by the upward displacement of air. ---------------------------------------------- The density of methane is 0,717 g/L and the density of air is 1,2 g/L at 0 0C; consequently methane gas raise in the air.
Are gasoline fumes heavier than air?
Bottled LPG is heavier than air That why it is recommended to place the gas bottle outside of the cabin. Any gas leaks from the bottle being inside, would collect in the bottom of the boat causing a very explosive mixture
Is methane lighter than air?
Yes methane is lighter than air because it is less dense than air.
Is methane heavier than crude oil?
No, methane is a very light gas and crude oil is certainly not
Are solvents heavier than air?
Yes solvents are heavier than air
Is breath heavier than air?
No, water is heavier than air.
Is argon heavier then air?
Yes, it is heavier than air.
Is natural gas heavier than air?
Is natural gas heavier than air
What is heavier than air flying craft?
"Heavier than air" refers to airplanes.
Does natural gas weigh more or less than air?
It weighs less than air. Density of air is 1.2 kg/m3, density of methane is 0.72 kg/m3 (at standard temperature and pressure). Natural gas is mostly methane but does contain small amounts of heavier hydrocarbons, ethane, propane, and butane, but the mean density is still less than that of air.
Which is a heavier-than-air flying craft?
An airplane is a heavier than air flying craft
