Physical & Chemical Changes

By Bailee Wilson

Physical Properties

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


EXAMPLES:

  1. Color and Shape
  2. Length and Mass
  3. Volume and Density

Physical Changes

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


Examples:

  1. Changing From One State of Matter to the Next(Ice Melts to Liquid, Liquid Boils to Steam)
  2. Melting 0 Degrees and Boiling 100 degrees C
  3. Slicing Bread, Melting Ice, and Mowing Lawn


Chemical Properties

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


EXAMPLES:

  1. Flammablilty (ability to burn)
  2. Reacts with Oxygen(ability to rust)
  3. Reacts with Light(pictures being developed)
  4. 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


EXAMPLES:

  1. Flammability(fire burning to ash)
  2. Reacts with Oxygen(fruit rotting)
  3. Heat and Light(vitamins can change exposed to light)
  4. Electricity(Water can be broken down with electricity)
