Condensing
hydogen
When water is in the form of a gas, it is called water vapour.
Condensation.
water vapour or steam
No there is no such tree, but the tree may have water on it that the sun evapourates it. water vapour.
When water is in the vapour form of steam, it is in a gaseous state.
sublimation. for example when camphor is heated at atmospheric pressure it will not melt but get sublimed into vapour phase. similarly it is possible to sublime ice into water vapour without converting into liquid-water by applying very low pressure.
Evaporate x
Greenhouse gases, carbon dioxide, water vapour, methane, etc.
The air needs to be cooled, the amount depending on how much water vapour is in it. When it's cooled sufficiently the water vapour will condense on solid things as water, or become very small droplets (fog/cloud). When this happens in the early mornings we call it dew, and the temperature at which the water will condense is known as the dewpoint.
It's called condensation. ( say: kon den sashun ) or: condensating! ( say: kon, den, ssate ing )
Water Vapour cannot immediately become solid, first it has to condense into a liquid as it drops below a temperature of 100 degrees centigrade, once it has dropped below a temperature of 0 degrees centigrade it then undergoes a process called freezing which is it condensing into a solid state. It is also the only known compound which is less dense in it's Solid State than in it's Liquid State
