A student cuts some fabric into two pieces. Is this change physical or chemical?(1 point)
Responses
It is a chemical change because there is no phase change.
It is a chemical change because there is no phase change.
It is a physical change because there is no reaction.
It is a physical change because there is no reaction.
It is a physical change because the process is reversible.
It is a physical change because the process is reversible.
It is a chemical change because the size changes.
It is a physical change because there is no reaction.
The correct response is:
It is a physical change because there is no reaction.
The correct answer is: It is a physical change because there is no reaction.
To determine whether the cutting of fabric is a physical or chemical change, we need to understand the difference between the two.
A physical change is a change in the physical properties of a substance without altering its chemical composition. It can usually be reversed, and there is no new substance formed. Examples of physical changes include changes in shape, size, or phase (e.g., solid to liquid).
On the other hand, a chemical change involves a rearrangement of atoms or molecules, resulting in the formation of new substances with different properties. Chemical changes are usually irreversible.
In the case of cutting fabric, there is no chemical reaction taking place. The fabric is simply being divided into two pieces, resulting in a change in shape and size. No new substances are formed, and the cutting process can be easily reversed by sewing the pieces back together. Therefore, cutting fabric is considered a physical change.
