What else can I help you with?
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
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.
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.
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.
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 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".
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.
