Investigating Chemistry

1

• Chemical change composition change
• Physical change no composition change,
  shape/form change
• Intensive properties Do not depend on the size
  of the sample
• Density is mass/volume.
• color, melting point, boiling point, odor,
  refractive index, hardness, texture, solubility,
  electrical properties, and density
• Extensive properties Do depend on the size of
  the sample
