What do these two changes have in common? a banana getting ripe on the counter mixing glue and laundry powder to create putty

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

C

Step 1: Think about each change. A banana getting ripe on the counter is a chemical change. As a banana ripens, the type of matter in it changes. The peel changes color and the inside becomes softer and sweeter. Mixing glue and laundry powder to create putty is a chemical change. The putty is a different type of matter that was not there before the change. 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. Neither change is caused by heating. Both are caused by cooling. Neither change is caused by cooling.
