What do these two changes have in common?
a puddle freezing into ice on a cold night
sewing an apron

 - Both are only physical changes.
 - Both are chemical changes.
 - Both are caused by heating.
 - Both are caused by cooling.
Step 1: Think about each change.
A puddle freezing into ice on a cold night is a change of state. So, it is a physical change. Liquid water freezes and becomes solid, but it is still made of water. A different type of matter is not formed.
Sewing an apron is a physical change. The fabric and thread that make up the apron get a new shape, but the type of matter in each of them does not change.
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.
A puddle freezing is caused by cooling. But sewing an apron is not.
