g/cm Physical Science 1 Chapter 1 VOLUME & DENSITY
· Volume is the amount of space an object occupies. Common units are cm or liter (L) and milliliter (mL). 3
1 mL=1 cm 1 L = 1000 mL 3
· Density is mass per unit volume of a material. Common units are g/cm or g/mL. Density= mass
m d= v o l um e
v · Density is directly related to mass of an object, and indirectly related to the volume of an object. Comparison of the volume of equal masses of 3 materials with different densities Comparison of the masses of equal volumes of 3 materials with different densities 3 Physical Science 1 Chapter 1 CONVERSION OF UNITS
· The SI system of units is easy to use because it is based on multiples of ten. · Common prefixes are used with the base units to indicate the multiple of ten that the unit represents. SI PREFIXES Prefixes mega kilo centi milli micro Multiplying factor 1,000,000 1000 0.01 0.001 0.000,001 Symbol M k c m m 4 Physical Science 1 Chapter 1 CONVERSION OF UNITS
· Any unit can be converted into another by use of the appropriate conversion factor, as shown below: beginning unit x fin uni al
= fin unit al
