PHYSICAL AND CHEMICAL CHANGES!!!!

By: Chloe Hale-1st Period

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 properties of a substance does not change.


Examples:

  • Changing from one state of matter to another (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.


Example:

  • Flammability (Ability to burn)
  • Reacts with oxygen (Ability to rust)
  • Reacts with light (Pictures being developed)
  • Reacts with water (medicine dissolving in water)

Chemical Changes

A change in the identity of a substance due to the chemical properties of that substance.


Example:

  • 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)
