Point to a cloud. Say, "That's made of the water that's in the air." If they don't believe you, wait for it to rain. Then tell them, "That's made of water that was in the air."

Why does an air cooler cool better on a hot dry day?
In a desert cooler, the water inside it is made to evaporate. This leads to absorption of energy from the surroundings, thereby cooling the surroundings. Again, we know that evaporation depends on the amount of water vapour present in air (humidity). If the amount of water vapour present in air is less, then evaporation is more. On a hot dry day, the amount of water vapour present in air is less. Thus, water present inside the desert cooler evaporates more, thereby cooling the surroundings more. That is why a desert cooler cools better on a hot dry day

Why does exhaled air saturated with water vapour?
water vapour is produce during respiration
Why are clouds not evaporated if they are water vapour?
Clouds are made up of water droplets of varying size, or ice crystals, not water vapour. Water vapour is the evaporite of clouds, and clouds often dissipate, so the water droplets making up the cloud change from visible water droplets to invisible water vapour. The "vapour trails" from aircraft engine exhausts are actually areas of cloud formation as water from burnt fuel condenses in cold air aloft.
What is the reason behind fog?
Actually, fog is a cloud of condensed water vapour present in the air. In cold days, water vapours become more cool to condensed by extracting its energy to its near by nitrogen vapours present in air (as boiling temperature of nitrogen is very low approx. -200C). Thus the condensed water vapour suspend in the air to make a cloud i.e. fog. O.P.Yadav GCET, Gr Noida
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
What is the amount of water vapour present in the air?
It is humidity.
What must be present so the clouds can form?
water vapour
Is water vapour is present in air only during the monsoon?
no
Is hydrogen present in air?
Yes, but in very small amounts. It is present in water vapour.
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.
Why does dust particles present in the air help water vapour to condense?
somehow
What would you see on Cobalt Chloride paper if water vapour was present?
Doubt it
What conditions must be present to frost to form?
water vapour/ cold /and a condensation medium
What is the amount of water vapour present in air called?
It is humidity.
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.
If a potted plant is covered with a glass jar water vapour appear on the wall of glass jar Explain why?
Because of transpiration. Transpiration is the evaporation of cellular water (in the form of water vapour) from the stoma in the leaves of the plants.
