Physical & Chemical Changes

By Emily Viss

Physical Properties

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


Examples:


  • Color and Shape
  • Length and Mass
  • Volume and Density (D+M/V)

Physical Changes

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


Examples:


  • 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, and boiling point
  • Slicing bread, melting, mowing lawn

Chemical Properties

Any characteristics that give's a substance the ability to undergo a change that result in a new substance.


Examples:


  • Flammability (ability to burn)
  • Reacts with oxygen (ability to burn)
  • Reacts with light (pictures being developed)
  • 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?)


Examples:


  • 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)
