1)Physical change
2)Chemical change]]> 2021-05-23 17:40:05 UTC https://padlet.com/ajeshchemistrylover/iz95zep3b27tn00d/wish/1551597911 CHARACTERISTICS OF PHYSICAL CHANGE ajeshchemistrylover https://padlet.com/ajeshchemistrylover/iz95zep3b27tn00d/wish/1551600130
  • Temporary in nature.
  • Does not affect the internal structure of a substance, only the molecules are rearranged.
  • No new substance is formed.
  • Most of the physical changes are reversible. We can obtain the substance back even after the change.
