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.
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 an another name for steam?
water vapour
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.
Is water vapour released through water vapour during transpiration?
Water vapor is released from the stomata of plant leaves during transpiration. Stomata are small openings on the surface of leaves that allow for the exchange of gases, including the release of water vapor as a byproduct of photosynthesis.
what is the molecular mass of water vapour?
The molecular mass of water vapour is 18.01528
Relative humdity is a ratio of what?
The mass of water vapour in a given quantity of air to the maximum mass of water vapour that it could hold - at the specific temperature and pressure.
Word for floating mass of water vapour?
Cloud.
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 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.
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.
Does water vapour take up more space than the same mass of liquid water?
All gasses take more place than the same mass of its fluid or steady fase. Here: vapour is not a gas, it is consisted of very small fluid parts!
How will you show that air has mass?
There are many ways to prove air has mass. One of them is : Take some water in a closed vessel and heat it till all the water boils. As we know when there is no transfer of particles mass remains constant. Therefore, the mass of the water vapour (air) is equal to the mass of the water taken. Hence, it is proved that air has mass.
What is water turned into gas called?
It is called water vapour or simply vapour.
What does water vapour do?
Water Vapour is a colourless, odourless gas which is made of tiny water droplets.
what does water vapour?
Water Vapour is a colourless, odourless gas which is made of tiny water droplets.
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.
