Air is heavier than water vapor.
Under certain condition (same pressure, temperature ...), the molecular mass of water vapor is 18 and the average molecule mass is approximately 29 (because in the air there are many gases with different mass)
Therefore: d(H2O/air) = M(H2O)/M(air) = 18/29 < 1
That means Water vapor is lighter than air, or vice versa.
What else can I help you with?
Water vapor makes up hat fraction of atmospheric gases?
The amount of water vapor in atmospheric gases is highly variable. More water vapor is found at lower altitudes, at 30,000 feet there is virtually no water vapor. There is a maximum of 4% water vapor in the atmosphere at any time.
How does air pressure affect how much water vapor air can hold?
Warmer air has higher saturation mixing ratios then cold air does. So therefore because of this 100% humidity in cold air is not 100% humidity in warmer air. The warmer the temperature, the more water vapor in the air. The colder the temperature, the less water vapor in the air.
What was the first earth's atmosphere made up of?
Primarily hydrogen, with probably water vapor, methane and ammonia.
How does water vapor in the air effect the weather?
Water vapor in the air is a key component of the water cycle and influences weather by leading to the formation of clouds, precipitation, and humidity levels. Higher water vapor content can lead to cloud formation and eventually rain or snow, while low water vapor content often results in clear skies and dry conditions. Water vapor also plays a role in the regulation of temperature and the intensity of weather systems.
Which holds more water vapor 12kg of air or 20kg of air?
At the Chemical Convention known as STP, or Standard Temperature and Pressure, 20 kg of Air contains more water vapor.
How does vapor affect air pressure?
Water Vapor affects pressure because moist air contains many heavy gases such as O2,N2 etc. But less water vapor. Since these gases are heavier than water vapor, it becomes more dense constituting more pressure. So Moist air contains less pressure than Dry Air.
Water vapor makes up hat fraction of atmospheric gases?
The amount of water vapor in atmospheric gases is highly variable. More water vapor is found at lower altitudes, at 30,000 feet there is virtually no water vapor. There is a maximum of 4% water vapor in the atmosphere at any time.
What is the relationship between the amount of gases in magma and the explosiveness a volcanic eruption?
The more gases, water vapor and silica there is in magma the bigger the explosiveness of a volcanic eruption.
Why metals corrode quickly near the sea?
There's more water vapor and other gases which cause corrosion.In water, they just go faster. -Neo
How is water linked to greenhouse gases?
Water vapor absorbs infrared heat in the atmosphere so it it classed as a greenhouse gas. However, man can not add water to the atmosphere, and water moves in and out of the atmosphere very quickly, so it can't be controlled. The natural water cycle is responsible for the movement of water and water vapor. As carbon dioxide and other greenhouse gases raise the temperature in the atmosphere more water vapor is able to rise into the atmosphere. This circular effect causes more warming than before.
What kinds of gases are on Earth?
Nitrogen(78%),Oxygen(21%),Carbondioxide(<1%),Argon(<1%) and Water Vapor(<1%) and many more.
How does air pressure affect how much water vapor air can hold?
Warmer air has higher saturation mixing ratios then cold air does. So therefore because of this 100% humidity in cold air is not 100% humidity in warmer air. The warmer the temperature, the more water vapor in the air. The colder the temperature, the less water vapor in the air.
Why does dry gas exert more pressure than moist gas?
Dry gas exerts more pressure than moist gas because water vapor in moist gas occupies space between gas molecules, reducing the frequency of collisions between gas molecules and the container walls. The presence of water vapor reduces the effective number of gas molecules hitting the container walls, resulting in lower pressure compared to dry gas.
What are the solute and solvent both gases?
When both the solute and solvent are gases, the solute is the gas that is being dissolved, and the solvent is the gas in which the solute is dissolved. An example is the dissolution of carbon dioxide (solute) in water vapor (solvent) to form carbonated water.
The primitive earth atmosphere is hypothesized to have consisted of?
The primitive Earth atmosphere is hypothesized to have consisted of gases like nitrogen, carbon dioxide, water vapor, and small amounts of methane and ammonia. These gases eventually formed the basis for the development of more complex atmospheric compositions and the evolution of life on Earth.
Why the gases are more soluble in cold water than they are in hot water?
gas is more soluble in cold water. In hot water, the molecules are farther apart, leaving room for gas to escape. That's why it's LESS soluble, and why hot water makes clearer ice cubes. Cold water molecules are close together, trapping in the gas and dissolving it. We keep pop in the freezer so the carbonation will last longer.
Which is more dense air saturated with water vapor or air unsaturated with water vapor?
Saturated air is more dense.
