Explanation:

Mixing chocolate syrup into milk is a physical change as no new substances are formed, just a mixture. A crayon melting in the sun is also a physical change as it changes state from solid to liquid without forming new substances. There is no chemical reaction in either case, and the crayon melting is due to heat from the sun while the chocolate - syrup mixing doesn't involve heating in the same sense.

Answer:

Both are only physical changes.
