What do these two changes have in common? melting wax picking up a paper clip with a magnet

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

C

Step 1: Think about each change. Melting wax is a change of state. So, it is a physical change. The wax changes from solid to liquid. But it is still made of the same type of matter. Picking up a paper clip with a magnet is a physical change. The paper clip sticks to the magnet, 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. Wax melting is caused by heating. But picking up a paper clip with a magnet is not. Both are caused by cooling. Neither change is caused by cooling.

What do these two changes have in common? a piece of pear turning brown baking cookies

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

A

Step 1: Think about each change. A piece of a pear turning brown is a chemical change. The substances in the pear react with oxygen in the air and turn into a different type of matter. If you scrape off the brown part of the pear, the inside will still be white. The inside hasn't touched the air. So the chemical change hasn't happened to that part of the pear. Baking cookies is a chemical change. The type of matter in the cookie dough changes when it is baked. The cookie dough turns into cookies! Step 2: Look at each answer choice. Both are only physical changes. Both changes are chemical changes. They are not physical changes. Both are chemical changes. Both changes are chemical changes. The type of matter before and after each change is different. Both are caused by heating. Baking is caused by heating. But a piece of pear turning brown is not. Both are caused by cooling. Neither change is caused by cooling.

Step 1: Think about each change. An iceberg melting is a change of state. So, it is a physical change. An iceberg is made of frozen water. As it melts, the water changes from a solid to a liquid. But a different type of matter is not formed. Baking cookies is a chemical change. The type of matter in the cookie dough changes when it is baked. The cookie dough turns into cookies!
