Physical and Chemical Changes

By Haley Bozorgnia

Physical Properties

Any characteristic of a material that can be observed or measured without changing the identity of the material.


  • Color and shape
  • Length and mass
  • volume and density(D=M/V)

Physical Changes

The physical property of a identity of the substance change,but the identity of the substance does not change.


  • Changing from one state of matter to the next.
  • Melting 0 degrees C,and boiling point 100 degrees C.
  • Slicing bread,melting ice,mowing lawn.

Chemical Properties

Any characteristics that gives a substance the ability to under go a change that results in a new substance.


  • Flammability
  • React to oxygen
  • Reacts with light
  • Reacts with water

Chemical Change

A change in the identity of a substance due to the chemical properties of the substance(IS IT REVERSIBLE?)


  • Flammibility
  • Reacts with oxygen
  • Heat and light
