Question

which process is an example of a physical change?
cutting carrots into pieces and mixed in a salad
sodium metal and chlorine gas combined to form salt
a peanut butter and jelly sandwich being digested
sodium metal and water combining to for a compound and gas

Explanation:

A physical change is a change in which no new substances are formed. Cutting carrots into pieces and mixing them in a salad only changes the physical form of the carrots. No new chemical substances are created. In contrast, combining sodium metal and water to form a compound, combining sodium metal and chlorine gas to form salt are chemical changes as new substances are formed. Digesting a peanut butter and jelly sandwich involves chemical reactions in the body to break down the food.

Answer:

Cutting carrots into pieces and mixed in a salad.
