Density

Density Ratio of mass to volume Formula D = M V Is a physical property so we can use it to identify substances D = density (g/mL or g/cm3) M = mass (g) V = volume (mL or cm3)

So is Density an Intensive or Extensive Property?

The density of water is 1.00 g/mL. If we half the amount of water, what will the new density be? http://onlyoneihave.blogspot.com http://thehealthydancer.blogspot.com

Density The heavier or larger density sinks Which one will sink, water or oil? Density at 20°C (g/mL) Water 1.00 Oil 0.82 Cork 0.24 Milk 1.031

Density The heavier or larger density sinks Ex: Which will float, water or cork stopper? Density at 20°C (g/mL) Water 1.00 Oil 0.82 Cork 0.24 Milk 1.031

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