It's called a physical change.
Melting, Boiling, Freezing, Condensation, sublimation, evaporation.
They all cause physical changes, but not "chemical" changes. Note, of course, some substances will decompose at temperatures lower than the Boiling point.
actually the question is not very clear to me if the questio is about the changes of physical state of a substance after a reaction then definitely the physical appearance of the substance will change while the chemical property remains the same. best example is burning of candle the wax melts changing apperarence of candle but the chemical composition of wax remains the same
Examples: boiling, freezing, sublimation, dissolution, etc.

It's a Physical Change =)

Physical, the chemical properties of the wheat are still the same.flour is ground by a physical change
no. its chemical properties do not change, only its apperance.
Physical and chemical change can have many positive effects on humans. The process of growth involves many reactions and visible changes, resulting in a stronger, more intelligent person.
Physical properties are characteristics of a pure substance that can be observed without changing it into another substance. Chemical properties are characteristics of a pure substance that describes its ability to change into different substance.
Physical properties are it's rest quantitative properties, while the chemical properties are its reactions to things like temperature and other substances. I hope somebody gives you a more comprehensive answer. :)
A physical change is a change that affects one or more properties of matter. For example, if you have a popsicle and it melts, it's looks change but the physical properties don't

Chemical properties describe how a substance will undergo chemical reactions and with what. Chemical changes are when one or more substances change to some other substance or substances.
A physical property is any characteristic of a material that can be observed or/and measured without changing the identity.A physical change is the change in which the properties of a substance change but the identity always stays the same.

group is more alike
Physical change is a concept introduced to contrast with the concept of chemical change. A physical change is any change not involving a change in the substance's chemical identity. Matter undergoes chemical change when the composition of the substances changes: one or more substances combine or break up (as in a relationship) to form new substances. Physical changes occur when objects undergo a change that does not change their chemical nature. A physical change involves a change in physical properties. Physical properties can be observed without changing the type of matter. Examples of physical properties include: texture, shape, size, color, odor, volume, mass, weight, and density. An example of a physical change occurs when making a baseball bat. Wood is carefully crafted into a shape which will allow a batter to best apply force on the ball. Even though the wood has changed shape and therefore physical properties, the chemical nature of the wood has not been altered. The bat and the original piece of wood are still the same chemical substance. Changes are sometimes hard to categorize strictly as physical or as chemical. Dissolving a salt in water involves the breaking of chemical bonds, yet is often described as a physical change. Some teachers hold that a chemical change is a rearrangement of atoms, but many physical changes also involve the rearrangement of atoms. Many chemical changes are irreversible, and many physical changes are reversible, but reversibility is not a certain criterion for classification. Although chemical changes are often recognized by an indication such as odor, color change, production of a precipitate, or production of a gas, every one of these indicators can result from physical change.
This involves a change of state of the water. Before, during, and after the boiling, it remains water. So, since the substance doesn't change its character, the boiling of water is a physical change.
false
what involves both chemical and physical change on earths surface
False. Properties within a group are more alike than properties within a period.
Drying (involving only the water evaporation) is a physical change.
