Why is there a limit on the amount of water vapor the air can hold?
It takes a lot of energy to turn water into water vapor. The amount of energy that the water gains to turn into water vapor begins to be transferred into the surrounding air. If the air is willing to take on more energy the water vapor condenses quicker. This is why hot air will hold more water vapor than cold air.
Does water vapor block solar energy?
Yes, the denser the cloud of water vapor, the more solar energy is blocked, or more accurately "reflected" back into space.
How are rain and water vapor different?
Water vapor is totally invisible. If you see a cloud, fog, or mist, these are all liquid water, not water vapor.Water vapor is extremely important to the weather and climate. Without it, there would be no clouds or rain or snow, since all of these require water vapor in order to form. All of the water vapor that evaporates from the surface of the Earth eventually returns as precipitation - rain or snow.When liquid water is evaporated to form water vapor, heat is absorbed. This helps to cool the surface of the Earth. This "latent heat of condensation" is released again when the water vapor condenses to form cloud water. This source of heat helps drive the updrafts in clouds and precipitation systems, which then causes even more water vapor to condense into cloud, and more cloud water and ice to form precipitation.
Does air pressure affect water 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.
What is the volume of 1 liter of water into vapor?
Q= 4.18(Kj/kg.C) x 1 (ltr) x(T2-T1) =Latent Heat of Vaporization = Hg - Hf = HfgRead more: How_much_heat_is_required_to_vaporize_1_liter_of_water
Why does water vapour have less density than dry air?
First you must understand "density." Density is the amount of atoms in a given volume. You can artificially create situations when there are more atoms in a given volume where the atoms are either "dry air" or "water vapor." But in ordinary situations, water vapor is mixed with what we call "air" and in ordinary situations, "dry air" has less water vapor in a given volume, so, people tend to say that water vapor is "heavy" or more "dense" than "air" or "dry air."
Which has more volume 10 kilograms of liquid water or 10 kilograms of water vapor?
Water vapour.Water vapour.Water vapour.Water vapour.
When 1 gram of water is evaporated the volume of the water vapor increases but the mass remains constant Why does the mass of the water remain constant?
Mass never changes unless you add more to it, the volume actually stays the same but is more spread out.
How does the water vapor content of air change with increasing temperature?
From what I think, as temperature increases, space between molecules of particles of air increases, which now has more space for water vapor to fit in. Also, as temperature increases, more water can evaporate to form vapor, so IF THE QUESTION IS IN RELATION TO A PLACE NEAR A WATER BODY, the water vapor content should increase.
An example of water turning into water vapor?
the process of water turning into water vapor is referred to as evaporation. It is a change in physical state of matter in which the molecules of water are heated up to the point at which they convert to the gas phase and become much more spread out and more more quickly. Gas has an indefinite shape and its volume disperses amongst its container (or lack there of).
Does the amount of water vapor that a volume of air can hold decrease as air temperature rises?
No. It increases. Warmer air can hold more water than colder air.
How does water vapor in the air effect the weather?
colder air doesn't collect as much water vapor
Which is more dense air saturated with water vapor or air unsaturated with water vapor?
Saturated air is more dense.
Which occupies the greatest volume 1g of ice 1 g of liquid water or 1g of water vapor?
1g water vapour occupies the greatest volume - even at high pressure. 1g of liquid water occupies the least volume. 1g of solid ice is greater volume than liquid water - and this is the only common liquid where the solid is of less volume than the liquid state.
Why is the density less in gases?
The particles (atoms or molecules) have more energy and move about more. They are thus more spaced out. Think of a pan of water. It occupies a small volume. Heat it up and the whole house can be full of steam/water vapor/gas. So the same mass has a lot more volume in a gas and as density is mass/volume the density is considerably lower.
What is humidity and how is it affected by temperature and pressure?
Simply humidity is percentage of moisture in atmosphere or in a gas.When temp. increases pressure reduces, that means gas percentage reduces in unit volume. But due to latent heat of water vapor expansion of vapor is less which results in increase in humidity. And when temp reduces, gaseous volume increases result in less humidity. The above case is for constant water vapor in air. If rain is there humidity increases because of chance of getting to water vapor is more.
What percentage of water vapor is in the earths atmosphere?
The % of water vapor is called Humidity. The attached link will give you more information.
