Density Chemistry Mrs. Coyle Density

Density= Mass Volume D= m

V Mass Mass: Amount of matter in a substance. Dont confuse with weight.

Weight: the force with which the earth pulls on the substance. Question Which weighs more?

50 kilograms of iron Or 50 kilograms of feathers Question

Which has a greater density? iron Or feathers

Common Units of Density Density= Mass Volume g/mL = g/cm3

1 cm3=1 mL 1 dm3=1L kg/m3

Densities of Common Substances Density as a Function of Temperature For most substances,

as temperature increases the volume increases and as a result the density decreases. Density of Water

Density of Water At 4oC water has its maximum density of 1g/cm3 Convert to kg/m3:

1000kg/m3 Note Density is an intensive physical property. (Does not depend on amount of matter in

the sample) Density Column Galilean Thermometer
