Physical and Chemical Changes

Physical Changes

A physical change is a change that does not change the substance. So, if you shred paper, it is still paper, but it is just shredded. A few examples are:

  1. shredding
  2. crumbling
  3. ripping
  4. cutting
  5. adding water
  6. changing the state of matter
  7. throwing/kicking

Chemical Changes vs. Physical Changes

These two are really different. Chemical changes are when an object changes substance. A physical change is when an object doesn't change substance, so it is still an object just changed in size, shape, color, and many more.

Chemical Changes

Chemical changes are when a substance completely changes. So, if you burn paper, it isn't paper anymore, it's ash. A few examples are:

  1. rusting
  2. rotting
  3. eating
  4. burning
  5. baking/cooking
  6. decomposing
