A student cuts some fabric into two pieces. Is this change physical or chemical? (1 point)
It is a physical change because the process is reversible.
O It is a chemical change because there is no phase change.
O It is a chemical change because the size changes.
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.
The correct answer is: It is a physical change because there is no reaction.
To determine whether a change is physical or chemical, you need to consider whether a new substance is formed or if there is a chemical reaction taking place.
In this case, when a student cuts a fabric into two pieces, no new substances are formed, and there is no chemical reaction occurring. The fabric is simply being physically separated into smaller pieces, but its chemical composition remains the same. Therefore, this change is considered a physical change.
