When air is cooled to the point where it cannot hold anymore water it starts to rain. evaporation is a cooling processes because it cools the air. Evaporation is a cooling processbecause when liquid turns to gas, it needs more energy, and so it has to take that energy from its surroundings. The energy is in the form of heat, and when the heat energy leaves with theevaporating liquid, the surroundings get cooler. the sun is responsible for unequal hearing in the water cycle.
A disaccharide (also called a double sugar or biose[1]) is the sugar formed when two monosaccharides (simple sugars) are joined. Like monosaccharides, disaccharides are soluble in water. Three common examples are sucrose, lactose,[2] and maltose.
Disaccharides are formed by the condensation reactions of two simple sugar molecules.
