Physical and Chemical Changes

By.RaeAnn Rankin

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 Change

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

  • Changing from one state of matter to the next. (Ice melts to liquid-liquid boils to steam)
  • Melting 0 degrees C, and Boiling Point 100 degrees C.
  • Slicing bread, melting ice, mowing lawn.

Chemical Properties

Any characteristic that gives a substance the ability to undergo a change that results in a new substance.

  • Flammability (Ability to burn)
  • Reacts with oxygen (Ability to rust)
  • Reacts with water (Medicine dissolving in water)

Chemical Change

A change in the identity of a substance due to the chemical properties of that substance. (You have a new substance) (Is it reversible?)

  • Flammability (Fire burning to ash)
  • Reacts with oxygen (Fruit rotting)
  • Heat and light ( Vitamins can change exposed to light)
  • Electricity (Water can be broken down with electricity)
