Answer

Brief Explanations:

Sewing an apron is a physical change as it only changes the shape and form of the fabric without altering its chemical composition. Snow - flakes forming in a cloud is also a physical change where water vapor changes its state from gas to solid (ice crystals) without a change in chemical identity. There is no heating or cooling as a common factor for both in a direct sense, and they are not chemical changes.

Answer:

Both are only physical changes.
