Given enough time and an average energy less than 100^@C, all the molecules in liquid water will become gas, and evaporate. Condensation is the return of molecules from the gaseous state to the surface of the liquid. For example, an individual water molecule will remain in suspension in the atmosphere. When enough water molecules join together, the molecules will form a rain drop or snow crystal and fall to the earth.
Condensation is the accumulation of water vapor changing to liquid water onto a surface. When. the interior temperature is warmer than the window surface, there is a chance that condensation will form. As the outside temperature decreases, the inside of the window surface will drop, causing the interior. window surface to be between the exterior temperature and the interior temperature. Since it is not. possible to control the exterior, the interior conditions must be controlled in order to prevent condensation.
