Suppose you have an internet friend who study chemistry just like you are your friend claims the change from liquid water to water vapor is a chemical change write a brief email that might convince your friends otherwise

When water is changed from a liquid to a vapor the chemical composition of the water does not change. When a water changes from a liquid to a vapor it still has the chemical composition H2O, thus making the change physical.

its first and third is your answer i did the qustion the fourth isnt right
