What do these two changes have in common?

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

C
|
Step 1: Think about each change.
Adding dish soap to water in a sink is a physical change. Bubbles may appear if air gets trapped in the soapy water, but a different type of matter does not form.
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 adding dish soap to water is not.
Both are caused by cooling.
Neither change is caused by cooling.
