<span>A condensation is a process where liquid changes into a gaseous form also known as water vapour. It occurs in the atmosphere when the temperature rises.
Water is produce when glucose and fructose undergo a condensation process. The water is removed by the combination of hydrogen and a hydroxyl together. Glucose and Fructose forms a substance called glycosidic linkage. And hydrogen and hydroxyl is separated from glucose and fructose. When Hydrogen and hydroxyl is combined, they create H2o or water.</span><span>
