Step 1: Think about each change.
Cutting a piece of rope is a physical change. The rope is shorter after you cut it. But it is still made of the same type of matter as the uncut rope.
Breaking a stick in half is a physical change. The stick gets broken into two pieces. But the pieces are still made of the same type of matter as the original stick.
Step 2: Look at each answer choice.
Both are only physical changes.
Both changes are physical changes. No new matter is created.
Both are chemical changes.
Both changes are physical changes. They are not chemical changes.
Both are caused by heating.
Neither change is caused by heating.
Both are caused by cooling.
Neither change is caused by cooling.
