17. the diagram below represents liquid water in a pan on a hot plate. the liquid water is boiling and changing into water vapor. the process of boiling is considered to be a a. chemical change, because a new substance is formed b. chemical change, because a new substance is not formed c. physical change, because a new substance is formed d. physical change, because a new substance is not formed

Answer

Explanation:

Step1: Understand physical and chemical changes

Physical changes do not create new substances, only change the state or form. Chemical changes create new substances through chemical reactions.

Step2: Analyze boiling of water

When water boils, it changes from liquid to gas (water - vapor). But both liquid water and water - vapor are composed of $H_2O$ molecules. No new chemical substances are formed.

Answer:

D. physical change, because a new substance is not formed
