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.

What does water vapor contain?
Water vapor is the gaseous form of water and contains molecules composed of two hydrogen atoms and one oxygen atom (H2O). It can also contain other substances present in the atmosphere, such as trace gases and particulates.
Is gas polar?
Yes, gas molecules can be polar if they have an uneven distribution of electrons leading to partial positive and negative charges. Examples of polar gases include water vapor and hydrogen fluoride.
What are some gases other than water vapor?
Some common gases other than water vapor include oxygen, carbon dioxide, nitrogen, helium, and methane. These gases are essential to Earth's atmosphere and play various roles in supporting life and maintaining the planet's climate.
Which of the following has greater entropy bromine vapor or liquid bromine Iodine vapor or solid iodine Justify your answer.?
Vapors always have more entropy than liquids of the same substance at the same temperature, because the number of energy states accessible to molecules in the vapor phase is much greater than in the liquid phase.
Is steam considered an ideal gas?
No, steam is not considered an ideal gas. Ideal gases follow the ideal gas law, which assumes that gas particles have no volume and do not interact with each other. Steam, on the other hand, consists of water vapor molecules that have volume and can interact with each other.
What does water vapor contain?
Water vapor is the gaseous form of water and contains molecules composed of two hydrogen atoms and one oxygen atom (H2O). It can also contain other substances present in the atmosphere, such as trace gases and particulates.
Are molecules that are farthest apart from each other called water vapor?
No, molecules that are farthest apart from each other are not called water vapor. Water vapor refers specifically to the gaseous form of water molecules. Molecules that are far apart from each other can simply be part of a gas phase.
What is inside the open spaces between the water vapor?
The open spaces between water vapor molecules primarily contain air, which is a mixture of gases such as nitrogen, oxygen, carbon dioxide, and trace gases. These gases occupy the same volume as the water vapor but do not interact with it in the same way, allowing for the exchange of energy and moisture. Additionally, in certain conditions, these spaces can also contain other particles like dust, pollen, and pollutants.
Is gas polar?
Yes, gas molecules can be polar if they have an uneven distribution of electrons leading to partial positive and negative charges. Examples of polar gases include water vapor and hydrogen fluoride.
Do continental volcanoes contain water vapor and other gases?
Yes, continental volcanoes can release water vapor and various gases, such as carbon dioxide, sulfur dioxide, and hydrogen sulfide, during eruptions. These gases can contribute to the explosive nature of volcanic eruptions and their potential to impact surrounding environments.
Why are the gases in the troposphere layer denser than the gases in the other layers?
The gases in the troposphere are denser than those in higher atmospheric layers because the troposphere is the lowest layer of the atmosphere, where air pressure is greatest due to the weight of the air above it. As altitude increases, the gravitational pull on air molecules decreases, leading to lower pressure and less density in the upper layers. Additionally, the troposphere contains a higher concentration of water vapor and other gases, contributing to its overall density compared to the stratosphere and beyond.
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.
Is water vapour compressible?
Yes, water vapor is compressible because its molecules can be forced closer together under pressure, reducing the volume occupied by the vapor. However, compared to gases, water vapor is less compressible because the molecules are closer together to begin with due to its high density in the gas phase.
How did volcanoes contribute to the creation of the initial oxygen in the atmosphere?
Volcanoes released gases like water vapor, carbon dioxide, and sulfur dioxide during eruptions. These gases reacted with sunlight and water vapor to form oxygen molecules, contributing to the initial oxygen in the atmosphere.
What are some gases other than water vapor?
Some common gases other than water vapor include oxygen, carbon dioxide, nitrogen, helium, and methane. These gases are essential to Earth's atmosphere and play various roles in supporting life and maintaining the planet's climate.
What four gases is the atmosphere made of?
i know two water vapor and other liquids
How is water vapor different from other gases that make up air?
Water vapor is the gaseous state of water, while other gases in the air, such as oxygen, nitrogen, and carbon dioxide, are distinct chemical elements or compounds. Water vapor can condense into liquid water or freeze into ice, depending on temperature and pressure, whereas other gases do not undergo similar phase changes under normal atmospheric conditions. Water vapor plays a crucial role in the Earth's weather patterns and the water cycle.
