Water vapor from air which naturally condenses on cold surfaces into liquid water is called dew. Water vapor will only condense onto another surface when that surface is cooler than the temperature of the water vapor, or when the water vapor equilibrium in air, i. e. saturation humidity, has been exceeded a cold bottle of water. The water molecule brings a parcel of heat with it. The temperature of the atmosphere also rises very slightly. In order to have condensed, the molecule tends to be relatively low in kinetic energy. Since the atmosphere has lost a slow-moving particle, the average speed of the molecules in the atmosphere has increased. Therefore, its temperature has also risen.
