  5. Physical Change • Change that happens without changing the identity of the object • The object has the same chemical formula • Changing states (solid, liquid, gas) • Chopping, Dicing, Slicing

  6. Chemical Properties • Hard to define! • The ability of a substance to undergo a reaction due to the elements that make up the substance.

  7. Chemical Change • Alters the composition of the original matter • It becomes a new substance!!!
