Which of the following is a sign of a physical Change?

A) The formation of a new substance

B) Breaking apart one substance into two substances

C) A change in the shape of a substance

D) The rearrangement of particles in a substance

The correct answer option is C) A change in the shape of a substance.

Explanation:

Physical changes can be defined as the changes which affect the form of a chemical substance but not its chemical composition. These are the changes in which no bonds are broken or formed.

A change in the shape of a substance is a physical change because there is no change in composition of the substance chemically.

While all other options involve a change in chemical composition so they are not the examples of a physical change.

C.) i believe because the change in shape is changing the physical appearance
