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.
What else can I help you with?
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.
How will you show that water vapour are present in air explain with help of diagram?
One way to show that water vapor is present in the air is by using a hygrometer, a device that measures humidity. The hygrometer will display the percentage of water vapor present in the air. You can also demonstrate this concept using a diagram by showing arrows representing water molecules in the air and indicating the percentage of water vapor present in relation to the total air molecules present.
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

Is the mass diffusivity of air in water vapour equal to that of water vapour in air?
No, the mass diffusivity of air in water vapor is different from the mass diffusivity of water vapor in air. The diffusivity of a substance in a medium depends on various factors such as temperature, pressure, and molecular weights of the substances involved, leading to different diffusion rates in different directions.
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 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
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
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 will happen if the density of air become less than that of water vapour?
Clouds cannot swim as they do now
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 do you prove that water vapour is present in the air by using only a beaker and several ice cubes?
Place the ice cubes in the beaker and wait for a few minutes. If water droplets form on the outside of the beaker, it indicates that water vapor in the air has condensed on the cold surface of the beaker. This condensation process proves the presence of water vapor in the air.
How does snow happen?
Snow forms when water vapor in the atmosphere freezes into ice crystals. These ice crystals then combine to form snowflakes. When these snowflakes become heavy enough, they fall to the ground as snow.
What is relative humidity a ratio of?
Relative humidity is the ratio of the partial pressure of water vapour to the saturation vapour pressure of water at the same temperature. Relative humidity depends on temperature and the pressure. Very roughly speaking, it is a ratio of the amount of water vapour in the air compared to the total amount of water vapour that it possible for that air to contain.
What is the amount of water vapour present in air called?
The amount of water vapor present in air is called humidity. Humidity is a measure of the water vapor content in the air, expressed as a percentage relative to the maximum amount of moisture that the air can hold at a specific temperature.
