Water vapor molecules are heavier than some gasses and lighter than others. The weight is based on their molecular weight which is the total of the atomic weights of the atoms in the molecule. The atomic weight of an atom is the total number of protons and neutrons in the atom.
Some examples:
Oxygen gas (O2) has has a molecular weight of 32 (two oxygen atoms each weighing 16) .
Hydrogen gas (H2) is 2 (two hydrogen atoms each weighing 1).
Water vapor (H2O) molecules have a molecular weight of about 18.
Helium (He) has molecular weight of 18.
Carbon Dioxide gas (CO2) is 44.

Are the molecules in water close to each other?
The molecules in water are closer to each other than those of water vapor, but farther away from each other than those of ice.
What characteristics would make a gas non-ideal?
The gas molecules interact with one another
Vapor pressure increases over a liquid in a closed container until?
Vapor pressure increases over a liquid in a closed container until the amount of vapor molecules rejoining the liquid equals the number leaving the liquid to form vapor. This is the characteristic vapor pressure of the substance.
Name at least four other gases in the atmosphere besides oxygen and nitrogen?
Argon, water vapor, CO2, and Neon.
Is water molecules same as water vapor?
yes
Do continental volcanoes contain water vapor and other gases?
All volcanoes emit water vapor and other gases.
How is water vapor different from other gases that make up air?
water vapor is different from other gases that make up air because it condenses out of air that has cooled
Allows the passage of water vapor and others gases into and out of leaves?
The opening and closing of the Stomata allows for water vapor and other gases to come into or out of leave.
How does the troposphere hold water vapor?
Water vapor is held by the troposphere in between molecules of atmospheric gases like oxygen, nitrogen and argon. Most of the water vapor in the troposphere is realized through transpiration off the earth's surface.
What four gases is the atmosphere made of?
i know two water vapor and other liquids
How are molecules moving from vapor to liquid?
Molecules speed up when they are turned from liquid into vapor. This is because they have more freedom to move around due to gaseous properties. Gases conform to the volume of the container, so they have more room to spread out, compared to liquids that do not have the ability to change volume
What is a example of gases?
Vapor
What is the process in which water molecules move away from each other to become whater vapor?
Condensation is the process by which water vapor in the air.
Are the molecules in water close to each other?
The molecules in water are closer to each other than those of water vapor, but farther away from each other than those of ice.
What is the concentration of greenhouse gases in the air?
The concentration of greenhouse gases in the air, largely water vapor, carbon dioxide and methane, are causing an enhanced greenhouse effect which is global warming.The amounts of greenhouse gases in the air are:5% Water Vapor0.039% CO2Trace (less then 0.001%) small amounts of other gases (methane, nitrous oxide etc)Water vapor absorbs heat like other greenhouse gases.
How liquid water ice and vapor differ from each other?
They are made of different kinds of molecules.
How water vapor released into the air beside evaporation?
Some other molecules can be carried in the atmosphere.
