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

It is not a chemical change because a chemical change is when the substance changes to a whole new substance (ex rust on a car) ex2(fire burning wood) it’s not the same substance) it is a physical change because it’s still water basically (ex: like melting ice, it’s still ice( not a whole different substance)
