What do these two changes have in common? ice melting in a glass getting a haircut

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

C

Step 1: Think about each change. Ice melting in a glass is a change of state. So, it is a physical change. The solid ice becomes liquid, but it is still made of water. A different type of matter is not made. Getting a haircut is a physical change. Your hair is shorter after a haircut. But it 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. Ice melting is caused by heating. But getting a haircut is not. Both are caused by cooling. Neither change is caused by cooling.

A

Step 1: Think about each change. Bending a paper clip is a physical change. After you bend it, the paper clip has a different shape. But it is still made of the same type of matter. Butter melting on a hot day is a change of state. So, it is a physical change. The butter changes from solid to liquid, but it 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. Butter melting on a hot day is caused by heating. But bending a paper clip is not. Both are caused by cooling. Neither change is caused by cooling.
