उत्तर
Water from oceans, rivers lakes from leaves of trees (transperation) changes into vapours when the temperature increases or evaporates and enters the atmosphere as clouds when the temperature falls the vapours change into the water and some of it in the form of snowfall on mountains and earth in the form of water and hales and this continues. Thus water cycle is an example of interconversion of states of water.
