Why does only the amount of water vapour change?
Changes in the amount of water vapor in the atmosphere are primarily influenced by temperature and air pressure. As temperature increases, more water can evaporate into the air. Similarly, changes in air pressure can also impact the capacity of the air to hold water vapor. Other factors, such as proximity to bodies of water or vegetation, can also affect the amount of water vapor in the atmosphere.
What is the process when water vapour changes to water called?
The process when water vapor changes to water is called condensation. This occurs when the water vapor in the air cools and transforms into liquid water droplets, usually forming on a cooler surface such as a window or a cold drink.
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 amount of water vapour in air called?
Humidity
The amount of water vapor in the air is called what.?
Humidity is the measurement of the amount of water vapour in the air.
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.
What is the amount of water vapour present in the air?
It is humidity.
What is the name of the amount of water vapour in the air?
humidity
How does water go to the air?
Water turn into a gas called water vapour. The air depending on its temperature will hold a certain amount of this. when the air comes into contact with water if the humidity of the air is such that it can hold more water vapour then the water that is touching the air will turn into the gas water vapour and become part of the air. it will do this at any temperature which explains why you can hang clothes out to drying sub zero temperatures and they dry.
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.
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 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 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 it called when water changes to vapour in the air?
Evaporation....
What is the vapor present in the air at a given temperature compared to the maximum amount that the air could hold at that temperature is called?
In the context of water vapour, it is "relative humidity".
