Question

what do these two changes have in common? sediment settling to the bottom of a muddy puddle sewing an apron select all that apply. both are only physical changes. both are chemical changes. both are caused by heating. both are caused by cooling.

Explanation:

A physical change alters the form of a substance but not its chemical composition. Sediment settling only separates solid sediment from water, no new substance forms. Sewing an apron rearranges fabric into a new shape without changing the fabric's chemical makeup. Neither change involves heating or cooling, nor are they chemical changes (no new substances are created).

Answer:

Both are only physical changes.
