  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

  2. 1 kg = 1000 grams 1 mm = 103 meter1 L = 1000 mL 1 cm = 102 meterOne pound is 454 g. One quart is 0.9464 L.One mile is 1.6093 km. One inch is 2.54 cm. UNIT Conversions
