Matter

States of Matter

Changes in matter

states of matter
States of Matter
  • Solid
  • Liquid
  • Gas
solids
Solids

Microscopic view of a solid

  • Definite volume
  • Definite shape
  • Atoms are packed together if fixed positions
  • Strong attractive forces between atoms
  • Only vibrate in place
liquids
Liquids

Microscopic view of a liquid

  • Definite volume
  • Indefinite shape
  • Atoms are close together
  • Atoms can overcome attractive forces to flow
gases
Microscopic view of a gasGases
  • Indefinite volume and shape
  • Atoms move very fast
  • Atoms are far apart
  • Weak attractive forces
changes in matter

Changes in Matter

Physical Change

Chemical Change

physical change
Physical change
  • change in a substance that doesn’t change the identity of the substance
    • Example: Includes all changes in the state of matter (physical changes of a substance from one state to another)
    • Grinding
    • cutting
    • Melting
    • boiling
chemical change
Chemical change
  • a change in which a substance is converted into a different substance
  • same as chemical reaction
  • doesn’t change the amount of matter present
signs of a chemical change
Signs of a chemical change
  • Energy is absorbed or given off (change in temperature)
  • change in color or odor
  • production of gas
  • Irreversible
chemical or physical change
Chemical or Physical Change?

physical

  • Water boils
  • Salt dissolves in water
  • Milk spoils
  • A metal chair rusts
  • Paper is torn
  • A tree burns down
