Answer
Ice melting is an example of a physical change.

The physical change is ice melting (option b). When ice melts, it simply changes its state from solid to liquid without altering its chemical composition.

Ice melting is a classic example of a physical change because it transforms from a solid state to a liquid state without altering its chemical composition. This transformation can easily be reversed—just freeze the water back into ice! It's all about the states of matter and the fun ways they can play with temperature. On the other hand, iron rusting is a chemical change where iron reacts with oxygen and moisture to form rust (iron oxide). Unlike melting ice, this process can't be easily reversed, making it a great reminder of how some changes are more permanent!
