Water in the form of vapor enter the atmosphere. The vapor accumulates in the atmosphere to form clouds. Once the clouds are heavy enough, the water in the form of droplets fall towards land or as rain. It could also be in the form of other precipitation such as snow or hail. As the sun hits the waters in the land, it causes the water to evaporate and the cycle continues.
Answer:
Water has properties of cohesion and adhesion.
Explanation:
The single Hydrogen atom and double Oxygen atoms attach to each other in such a way their are minute polar polarity differences. Electron bonds will combine to form one side of the compound as being positive and the other side positive. Positive side of other H2O molecules will attach to the negative side. This bond causes water to adhere to sides of a glass test tube.
Will also create a bead when it drips on another non-porous surface. Adding soap will break the bead (surfactant). Water is the perfect solvent.
