Dissolve

The word dissolve can mean:

 In chemistry, it is the act of solvation, when a solid is mixed into a liquid, creating a  solution. Mixing salt into water is an example.  Upon evaporation, the dissolved parts usually come out of solution and reform the solid.
 In film and video editing, it is one way of changing the view. For example, a scene fades (changes slowly) from a bright day to all black.
 In politics or law dissolution means that something is brought to an end, either permanently or so that a new election can happen.
