How can you say that water vapour are present in air give an activity to explain it?
One way to show that water vapor is present in the air is to cool the air. If the air temperature drops below its dew point, water vapor in the air will condense into tiny droplets, forming visible fog or mist. This process demonstrates that water vapor is a component of the air.
Why does a desert 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.
What will happen if water vapour is not present in air?
If water vapor is not present in the air, it would be considered dry air. This would result in lower humidity levels, which can lead to dry skin, irritated eyes, and respiratory issues for some individuals. Additionally, lack of water vapor in the air can impact weather patterns and precipitation.

Solid condensation on a surface that is below 0C is known as?
Water vapour changing to solid on a surface is sublimation of the vapour. For water the product is referred to as rime or hoarfrost.
What is the amount of water vapour present in the air?
It is humidity.
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 must be present so the clouds can form?
water vapour
Why does dust particles present in the air help water vapour to condense?
somehow
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 conditions must be present to frost to form?
water vapour/ cold /and a condensation medium

How do you know that water vapour is present in the air?
it will often be in the form of steam so it will be thicker and heavier
What is the nutrient present in sewage?
What are the nutrients present in sewage? What are the by products of waste water treatment? Name a plant which can absorb waste water rapidly and release pure water vapour to the atmosphere.
Matter can exist in only three phases called what?
The tree phases of a matter are called Solid, liquid and gas. For example, water is present in the form of Ice, liquid water and water-vapour or steam.
What do the lines on a phase diagram present?
what happens to water molecules when they are heated
What is water turned into gas called?
It is called water vapour or simply vapour.
