This is an example of a change in the physical states of Matter. These states-of-Matter are: Solid, Liquid, Gas and the Newest and Latest and most energetic State - Plasma. Frost is a special 'case' because it does not Condense [vapor to liquid], it Sublimes - water [in this case] vapor crystallizing [directly] to the Solid - bypassing the liquid phase.
When milk turns sour, it is a chemical change because the bacteria in the milk ferment the lactose sugar into lactic acid, which changes the composition of the milk. This process cannot be easily reversed, making it a chemical change rather than a physical one.
Iron rusting is a chemical change: oxidation of the metal by oxygen in the air or water. When iron 'rusts' it oxidises. This is a chemical change, a physical change is when a molecule changes state, for example iron melting and going from a solid to a liquid.
A physical change is a change in chemical composition. A physical change is a change where chemical composition is not altered. Not all chemical changes are accompanied by a physical change, but some are. The same is true for the reverse.

it is a physical change most of the times because you can get i back into its original form. for ice, or plastic... its physical. but for styrofoam, its a chemical change because you cant get it back.
Then the physical characteristic of a substance change, it is called a change in state. This most commonly occurs when a substance is heated or cooled. The states that substances are solid, liquid and gas. A common example would be water: ice (solid), water (liquid), and steam (gas).
The physical property can be measured and quantified. It includes things like melting point, texture, color... A physical change is when a physical property is altered. The most common example is a change in physical state usually from a temperature change (solid melting to a liquid). A physical change does NOT alter the actual substance. (It's still water just in a different form.) MLZ Carpenter, Ph.D.
The most important thing for your to remember is that in a physical change the composition of a substance does not change and in a chemical change the composition of a substance does change.
The comparative form of "clearly" is "more clearly," and the superlative form is "most clearly." These forms are used to compare the clarity of actions or statements among two or more subjects. For example, you might say, "She explained it more clearly than he did," or "He explained it most clearly of all."

"The answer is clear to me."
Dissolving is considered by most to be a physical change.
B
more clearly, very clearly, the most clearly
