Does anyone have a detailed explanation on condensation? i do not really understand......

What is it that you do not understand about Condensation?

In its most basic definition, condensation is the process of changing from a gaseous to a liquid or solid state. However, depending upon what you are having problems with, there could be much more information added to that statement. For example, you may wish to know about when condensation occurs, not just the simple definition of what it is. Or the factors that affect condensation.
