Answer 1

Chemical change is what happens when a new material is created. A chemical change happens due to chemical reactions. The atoms in a substance during a chemical reaction is rearranged or arranged differently from the original and usual arrangement. One of the examples is when water is frozen and solidify becoming an ice. Water is liquid with atoms arranged away from each other and it changes or transforms into a different substance which is solid which means the atoms are more compressed than those that of liquid.
