Density

Density Ratio of mass to volume Formula D = M V Units in chemistry are g/mL or g/cm3 Is a physical property so we can use it to identify substances

So is Density an Intensive or Extensive Property?

Density The heavier or larger density sinks Ex: water and oil Density at 20°C (g/mL) Water 1.00 Oil 0.82 Cork 0.24 Milk 1.031

Density Which will float water or cork stopper? Density at 20°C (g/mL) 1.00 Oil 0.82 Cork 0.24 Milk 1.031

Density Which will sink water or milk? Density at 20°C (g/mL) Water 1.00 Oil 0.82 Cork 0.24 Milk 1.031

Viscosity Is the resistance to flow Is an Intensive Property Example: Syrup vs Water Is an Intensive Property
