Which process is a chemical change?

Chemical Change. Chemical changes occur when bonds are broken and/or formed between molecules or atoms. This means that one substance with a certain set of properties (such as melting point, color, taste, etc) is turned into a different substance with different properties.

Which of the following is an example of chemical change?

A change in which a substance undergoes a change in its physical properties such as shape, size, color, and state is called a physical change. A physical change is generally reversible, (some exceptions). In this change, no new substance is formed. Example: An ice cube melting into water.

Why is it called a physical change?

Physical changes occur when objects or substances undergo a change that does not change their chemical composition. This contrasts with the concept of chemical change in which the composition of a substance changes or one or more substances combine or break up to form new substances.

Why is crumpling paper a physical change?
