For an Accurate Reading you would need a proper Humidity Sensor, howerver you can get a reading off a combined temperature, Humidity and pressure Dials on a kind of clock With needles some people have them in their porches. you can buy them they not that expensive..

How do you prove that water vapour is present in the air by using only a beaker and several ice cubes?
When ice cubes are kept in beaker the water vapour in the air condenses on the outer walls of the beaker.this shows the presence of vapour in air.
Can water vapor rust iron?
Rusting will only occur in the presence of both water and oxygen. In the presence of oxygen, water vapour in the air will cause rusting to occur. So unless you are talking about the iron coming into contact with water vapour but when there is no oxygen, the answer is yes.
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
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 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.
Why is it that you can see clouds but you can not see water vapour in the air?
You can see water vapour in the air, as when a kettle or pan boils, or when you breathe out into cold air. It depends on the temperature balance between the vapour and the surrounding air.
Why does exhaled air saturated with water vapour?
water vapour is produce during respiration
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 specific humidity and relative humidity?
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.
What is the name for gaseous water in the air?
water vapour
What is the name for the water gas in the air?
Water vapour.
How much more solar energy is absorbed by air than is reflected by air?
Backscattered of air would reduce 8% of solar intake, 19% is absorbed by air due to presence of aerosol, CO2 and water vapour.
