The water vapor cools and at the dewpoint it condenses and fog forms. Water vapor condenses more rapidly in colder air. The water vapor in the air contacting this cold water condenses into fog. The dew point is a temperature at which a vapor condenses into a liquid. Water vapor condenses on the outside of the tubes as product water. Cyanic acid polymerizes to cyanuric acid, which condenses with the liberated ammonia forming melamine. Hot vapor condenses on the upper section of the Erlenmeyer flask, reducing solvent loss. The gaseous sulfide condenses on the crucible fabric. This energy transfer process decreases the temperature of the refrigerant that, in turn, condenses. More moisture condenses on the coils, dehumidifying the air. The acetone condenses evenly all over the part, causing the surface to soften and liquefy. It condenses on the underside of the glass and drips to the bottom. The medullary cord condenses, separates and then forms cavities. During cell division chromatin condenses further to form microscopically visible chromosomes. The ammonia also condenses and is separated in a pressure separator.
