What is the difference between a chemical and physical change? Chemical changes involves the production of an entirely new substance through breaking and rearranging atoms. Physical changes are usually reversible and do not involve the creation of different elements or compounds.

Both: They both invlove changes in the state of matter. They both have energy changes. There are new things made either way, no matter if the chemical composition is changed or not.

Physical properties include odor,taste,appearance,melting point,boiling point etc.. where as chemical properties include the chemical reaction,changes at molecular level. ... During the physical change neither the chemical composition nor chemical nature of the substance changes.

However, a catalytic property would also be a chemical property. Chemical properties can be contrasted with physical properties, which can be discerned without changing the substance's structure. ... They can also be useful to identify an unknown substance or to separate or purify it from other substances.

Rust is clearly a substance that is different from iron. Rusting is an example of a chemical change. ... However, unlike physical properties, chemical properties can only be observed as the substance is in the process of being changed into a different substance. A chemical change is also called a chemical reaction.

At the molecular level, chemical change involves making or breaking of bonds between atoms. These changes are chemical - for example, iron rusts and iron oxide is formed. ... Chemical reaction is a process of changing from one chemical state to another and chemical change is a change in the state of a material.

A chemical property is a characteristic of a substance that can only be observed during some type of chemical reaction. For example, compounds can have a reaction to acid, a reaction to light or a reaction to heat. How well a substance burns, in other words its flammability, is also a chemical property.

Rust is clearly a substance that is different from iron. Rusting is an example of a chemical change. A chemical property describes the ability of a substance to undergo a specific chemical change. A chemical property of iron is that it is capable of combining with oxygen to form iron oxide, the chemical name of rust.

Physical changes only change the appearance of a substance, not its chemical composition. Chemical changes cause a substance to change into an entirely substance with a new chemical formula. Chemical changes are also known as chemical reactions.
