What do these two changes have in common?
water boiling on a stove
breaking a plate

 - Both are caused by heating.
 - Both are only physical changes.
 - Both are caused by cooling.
 - Both are chemical changes.
Step 1: Think about each change.
Water boiling on the stove is a change of state. So, it is a physical change. The liquid changes into a gas, but a different type of matter is not formed.
Breaking a plate is a physical change. The plate gets broken into pieces. But each piece is still made of the same type of matter.
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.
Water boiling is caused by heating. But breaking a plate is not.
Both are caused by cooling.
Neither change is caused by cooling.
