Answer 1

Answer:

Both are only physical changes

Explanation:

Answer 2

Sediment settling to the bottom of a muddy puddle is a physical change and a puddle freezing into ice on a cold night is also a physical change. Both are only physical changes.

What is Physical change ?

These changes are temporary in nature. In physical change no new substances formed. It is reversible change. Sediment settling to the bottom of a muddy puddle is a physical change and a puddle freezing into ice on a cold night is also a physical change. Both are only physical changes.  

What is Chemical change ?

Chemical change are those changes in which substance changes chemical composition. These changes are permanent changes. In chemical change new substances formed and in chemical change substances can not get back into its original form. It is irreversible change. Sediment settling to the bottom of a muddy puddle and a puddle freezing into ice on a cold night both are not chemical changes as there is no new substances formed.

Thus, from the above conclusion we can say that Sediment settling to the bottom of a muddy puddle and a puddle freezing into ice on a cold night both are only physical changes.
