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.
Cool a sheet of metal and leave it in the room, if the air contains water vapour it will condense on the cold metal.
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.
Relative humidity compares the amount of water vapour present in the air with the amount of water vapour that would be present in the same air at saturation. Specific humidity is the mass of water vapour present per kg of total air.
Water vapour.
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.
you would say the air was humid
It contains the potential of ways
Rising air contains water vapour which condenses as the air cools with altitude.
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.
Contains normal air composed of N2, O2, water vapour, CO2, etc.
Cool a sheet of metal and leave it in the room, if the air contains water vapour it will condense on the cold metal.
Condensation of water vapour in the atmosphere into water droplets on the surface. The surrounding air contains water vapour. When the air touches the glass it becomes cooler and can no longer contain so much water, so it condenses out onto the glass.
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
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.
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.
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.
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.
