Because of transpiration. Transpiration is the evaporation of cellular water (in the form of water vapour) from the stoma in the leaves of the plants.
Henry's law states that, the partial pressure of the gas in vapour phase is proportional to the mole fraction of the gas in the solution.
The molecular mass of water vapour is 18.01528
If you look carefully at a boiling kettle, water vapour is the white vapour you can see. Steam is actually the invisible short section between the spout of the kettle and the start of the water vapour.
70.8% of the Earth's surface is covered by water while there is much less water on other planets in the solar system, such as small amount of water vapour on Venus, small amount of ice on the moon, mars , jupiter, saturn etc.
the difference is that water vapour is just one particle that joins together with more and more to form steam
Venus
Water vapour from your breath and other sources condensing on cold glass, the glass becomes covered in a thin layer of water.
No. Vapour does not smell.
Henry's law states that, the partial pressure of the gas in vapour phase is proportional to the mole fraction of the gas in the solution.
The water vapour condensed on the windows. The vapour rising off the acid made me choke.
Anything evaporated would be funnelled upwards where the vapour could be collected if a tube was to be fastened to the funnel .
Any vapour is compressible.
no
that's because there becomes possibility of vapour formation and thermal expansion of petrol in the tank that is more flammable than petrol in liquid form and therefore wastage of petrol due to vapour formation is severly reduced
No, air bubbles will not appear when reheating boiled water. The boiling process releases dissolved gases, so when the water is reheated, there are no air bubbles left to be released. The lack of dissolved gases makes it appear that air bubbles do not form when the water is reheated.
Whi many are, many are not (iodine vapour is quite easily seen, for example, where water vapour is not).
I expect you mean iodine vapour. Please see the link.
