Density Notes

 

Density is a measurement of how much matter is packed into a certain volume of a substance.

  • The most common unit of density is grams per cubic centimeter (g/cm3)
  • Grams per milliliter are also common. *1cm3 = 1mL

 

The density of a substance mostly stays the same. For this reason, knowing the density of an object may give you a clue as to what the object is made of.

Density is also useful for predicting if something will sink or float in water.

  • Pure water has a density of 1g/cm3 .

Materials with a density greater than water sink in water.

Materials with a density less than water float in water.

**Corn oil, with a density of only 0.93g/cm3, floats in water.

 

*Science Alert! The density of a material changes with temperature. Ice (0.9g/cm3), for example, is less dense than liquid water (1.0g/cm3 ). For most other materials, density increases as temperature decreases.
