Accepted Answer

Welcome back, everyone. We're told to classify the following changes as physical or chemical, which is slicing a cake into eight parts. So let's go ahead and recall how to define first a physical change. So recall that for a physical change, this will involve a change in size where we're using our delta symbol to represent change. We can also have a change in volume and we can also have a change in state whether we're going from our solid form of our substance to its liquid form or to its gaseous form. These are all describing physical changes. Next, let's recall what a chemical change involves. We should recall that this will involve specifically a change in chemical property. So with a change in chemical property, this will correspond to the formation of new bonds most likely or the formation of new substances. And so with this, with these fox outlines for both physical changes and chemical changes. If we are slicing a cake into eight parts, this is just describing a change in size as well as the change of the state of our cake now, which is now in eight slices or parts. So because we have a change in size and state, we therefore have a physical change. So physical change is going to be our final answer when you slice a cake into eight parts. I hope this makes sense and let us know if you have any questions.
