What do these two changes have in common? baking cookies melting wax

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

C

Step 1: Think about each change. 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! 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. Step 2: Look at each answer choice. Both are only physical changes. Melting wax is a physical change. But baking cookies is not. Both are chemical changes. Baking cookies is a chemical change. But melting wax is not. Both are caused by heating. Both changes are caused by heating. Both are caused by cooling. Neither change is caused by cooling.
