Cold air (vapour) is heavy and presses down. Warm air (vapour) is lighter and rises..Vapour condenses when it meets cool air. High in the atmosphere the air is thinner and colder. If the air is thinner, then the vapours are spread out. Weather happens in the lowest part of the atmosphere. Cold vapour is thick and heavy, eg: it is cold at the top of the cumulonimbus thunder cloud which appears when the atmosphere is full of water. When warm rising air meets thick heavy cold air, water droplets condense (fall) out of the air. From which air does the water condense, the warm air, or, the cold air? When warm air rises and meets cooler air, water vapour condenses into liquid from both the cold and the warm air. Experiment: Place the tip of your warm dry finger on an ice block, notice how the tip of your finger gets wet. The warmth from your finger caused the ice to melt (water to come out of the cold ice). Take a cold can of drink out of the freezer and within a few moments water vapour will condense out of the air and appear on the surface of the can. Now I haven't put my warm finger into extremely cold air (vapour) but I am sure that if I did, when I took it out, it would have drops of water upon it. Dont put your fingers into extremely cold vapour, because you could get, frost bite. Frost bite: Destruction of tissue caused by cold. esp. of the ears and fingers. http://www.oocities.org/noelenejoy/my-index.html http://www.oocities.org/noelenejoy/my-index-page-1.html Any errors within my pages are not intentional |
