What do these two changes have in common? stretching a rubber band water evaporating from a puddle

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

D

Step 1: Think about each change. Stretching a rubber band is a physical change. The rubber band gets longer. But it is still made of the same type of matter as before. Water evaporating from a puddle 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. 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 evaporating is caused by heating. But stretching a rubber band is not. Both are caused by cooling. Neither change is caused by cooling.
