Put a bottle of water inside your refrigerator and let it cool down. After that, take it out and notice how the surface of the bottle becomes moist. That is water.

Yes under typical atmospheric conditions, water vapor is continuously generated by evaporation and removed by condensation.

How are weather systems dependent on water?
Because water vapour contains the latent heat of evaporation which is released back into the air when water condenses. It is this heat that drives the storms.
What is the name for the water gas in the air?
Water vapour.
How is relative humidity affect by air temperature?
Warmer air is able to hold more water vapour than cooler air. As warm humid air cools, the water vapour condenses out as water droplets.
What is specific humidity and relative humidity?
Specific humidity is the mass of water vapor present in a unit mass of air. It is expressed in grams of water vapor per kilogram of air. Relative humidity is the ratio of the amount of water vapor present in the air to the maximum amount of water vapor the air can hold at a given temperature, expressed as a percentage.
What is the Troposphere made out of?
- The lowest layer (about 15 km from the ground) - Contains normal air composed of N2, O2, water vapour, CO2, etc.
How can you say air contains water vapour?
you would say the air was humid
What is occurring when you can see your breath on cold days?
The air that you exhale contains water vapour. When you exhale during a cold day, the relative humidity increases. Relative humidity is actually the percentage of the amount of water vapour in the air.(the maximum amount of water vapour that the air can hold at that temperature) The colder the air, the less water vapour it can carry. When exhaled, air mixes with cold air, the temperature of the exhaled air drops, but there is more water vapour. When the air becomes saturated, (relative humidity is 100%), the extra water vapour will condense, allowing you to see your breathe on cold days.
What is in the troposphere?
Contains normal air composed of N2, O2, water vapour, CO2, etc.
Why can you see clouds but not water vapour in the air?
It is because water vapour is air so it can't be seen but when we breath out in the mirror,water vapour is found.
What percentage of dry air is water?
Ordinary room air will have only about 4% of water vapour in it, but this can increase quite a lot before the air feels uncomfortable.Relative Humidity is the usual measure of the amount of water vapour in the air, and can vary from a few% (normal) to over 90% (humid). At 90%, the air is NOT 90% water vapour; that figure indicates that the air contains 90% of the amount of water vapour it could contain when fully saturated.For very low percentages of water vapour in the air, (say below 1%) a useful measure and one more easily made, is to measure the dew point of the air. For this, the instrument contains a small shiny mirror that may be cooled to the point where dew just forms on the mirror surface, thus spoiling the reflection.
The excretory system why do you see your breath on a cold day?
The air that you exhale contains water vapour. When you exhale during a cold day, the relative humidity increases. Relative humidity is actually the percentage of the amount of water vapour in the air. (the maximum amount of water vapour that the air can hold at that temperature) The colder the air, the less water vapour it can carry. When exhaled, air mixes with cold air, the temperature of the exhaled air drops, but there is more water vapour. When the air becomes saturated, (relative humidity is 100%), the extra water vapour will condense, allowing you to see your breathe on cold days.
What refers to the amount of water vapour in the air?
Relative Humidity is the measure of water vapour in air. It is the ratio of the actual water vapour in air divided by the maximum amount the water the air can hold at the existing temperature and pressure. It tells how fast or slow the water on the body or in clothes will evaporate or in otherwords is the air dry or humid. Absolute measure of water vapour in air is called specific humidity. It can be measured as ratio of mass of water and mass of dry air.
How go you know that the air exhaled by us contains water vapour?
because it condenses into water when your hot breath is exhaled onto a cold object.
Is water vapour a liquid?
Water vapour is not completely a gas.It contains a lot of water.But it can also be said as a gas........
In addition to gasses what else does the air contain?
In addition to gases air contains: dust particles, water vapour, pollen grains, particulate pollutants etc.
How are weather systems dependent on water?
Because water vapour contains the latent heat of evaporation which is released back into the air when water condenses. It is this heat that drives the storms.
Is water vapour not one of the constituents in air?
Water vapour is a constituents in air because water vapour rises in the atmosphere & is always present in the atmospere in some or the other quantity.Also 0.0001% of air consist water vapour
