This would be an example of a physical change because the pumpkin's physical form is altered, but its identity as a pumpkin remains the same. The pumpkin is not transformed into a different substance.
Explicação
## Step 1The problem is asking us to identify whether the act of cutting a face into a classroom pumpkin is a physical or chemical change. To answer this, we need to understand the definitions of both physical and chemical changes.## Step 2A physical change is a type of change in which the form of matter is altered but one substance is not transformed into another. This means that the substance's identity remains the same, even though its physical appearance may change.## Step 3A chemical change, on the other hand, is a type of change where one or more substances are converted into new substances. This means that the substance's identity is altered, and new substances are formed.## Step 4In the case of cutting a face into a pumpkin, the pumpkin's physical form is altered, but its identity as a pumpkin remains the same. The pumpkin is not transformed into a different substance, so this is a physical change.
