What do these two changes have in common? water boiling on a stove a puddle freezing into ice on a cold night

[ "Both are caused by cooling.", "Both are only physical changes.", "Both are chemical changes.", "Both are caused by heating." ]

B

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. 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. 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 a puddle freezing is not. Both are caused by cooling. A puddle freezing is caused by cooling. But water boiling is not.
