Explanation:

Answer:

Both are only physical changes.
Both conserve mass.

(Note: "Both are caused by heating" is incorrect for pouring milk on oatmeal (it’s a physical mixing, not necessarily caused by heating), and "Both are chemical changes" is incorrect as both are physical changes. So the correct ones are "Both are only physical changes" and "Both conserve mass".)
