The change of cutting the fabric into two pieces is a physical change because there is no reaction occurring. Additionally, the process of cutting can be reversed by sewing or reattaching the fabric pieces together.
To determine whether cutting fabric into two pieces is a physical or chemical change, we need to understand the characteristics of each type of change.
A physical change is a change in a substance's appearance or form without altering its chemical composition. In this case, cutting fabric only changes its size or shape, but it does not alter the fabric's chemical makeup. The fabric remains the same material before and after it is cut. Therefore, we can conclude that cutting fabric is a physical change.
To reach this answer, we need to consider that a chemical change involves a reaction that causes a change in the substance's composition, while a physical change does not. In the case of cutting fabric, no chemical reaction occurs, nor is there any change in the fabric's chemical properties.
So, the correct answer is: It is a physical change because there is no reaction.
