What is condensation & Common process for evaporation and condensation

2.Common process for evaporation and condensation


1. What is condensation?
When you pour some icy (chilled) drink into a tumbler, you will discover a few beads sparkling on the external side of the tumbler, be that as it may, precisely you pour it. Do you know why it so happens?Take a tumbler and fill half of it with water. Presently put some ice-3D squares into it and sit tight for at some point. The ice will dissolve and begin cooling the water and additionally the tumbler. 

 
Before long, you will find that the external mass of the tumbler—so far entirely perfect—has now some sparkling beads of water on it. Where have these beads originated from on the external mass of the tumbler? Additionally, you will see that the hotter the environment, the all the more rapidly the beads will sparkle on the external side of the tumbler and in more noteworthy number. 

You have effectively comprehended the procedure of dissipation by prior tests. On all untamed water surfaces, this procedure goes on; the procedure in which water changes to vapor shape and gets assimilated in the environment. Be that as it may, at whatever point it comes into contact with a cool surface, it returns into the fluid frame like the beads you saw on the tumbler. This ensuing procedure is known as buildup. With the expansion in temperature, the procedure of dissipation additionally accelerates. Likewise, the procedure of buildup is additionally speedier in the event that it happens on a cooler surface

2. Common process for evaporation and condensation
Amid downpours, a great deal of water tumbles from the sky. Once in a while, the rain proceeds for quite a long time. Where does as such much water originate from?For this examination, it would be better on the off chance that you could acquire one aluminum pot for heating up the water. Something else, any vessel can fill the need. Cover it with a top in a manner that there remains a little hole between the top and the vessel for the exit of the steam. Presently heat up the water till the steam begins turning out. Take a few bits of ice or chilled water in a skillet with a handle. 
 
Presently observe from where the rain water comes in the sky. Hold the skillet at some separation from the spout of the pot smothering the steam and see what happens. The hot steam strikes the external chilled mass of the container and gets changed over again into water drops, i.e., the procedure of buildup happens. At the point when numerous such drops join together and turn out to be too substantial to withstand their own weight, they begin tumbling to the ground. This decisively is the procedure by which the rain falls. 

The warmth radiating from the sun changes over the water of the streams, lakes and the oceans into vapor and in this manner, water as vapor gets retained in the air. As the air climbs, it gets to be colder and the vapors exhibit in it takes the state of modest drops of water  from the colder atmosphere above. An extensive accumulation of such water drops frames the cloud. At the point when the water drops in the cloud turn out to be too substantial to withstand their own particular weight, they begin tumbling to the earth and in this manner; we get the pleasure of downpours.
