1. Particles and Density
How does the arrangement of particles effect density ?
How is density calculated ?

2. What material has the greatest density ?

3. Density is how much mass is packed into a certain space or volume.
Density is measured in g/cm3 or kg/m3.
Water density at 200C is 1g/cm3.
Copper density at 200C is 8.92g/cm3.
Density of lead at 200C is g/cm3.

4. Gas Density and State Solid Liquid
Most substances get less dense as their temperature increases and they change state.
Gas
Liquid
Solid

5. ….. except water !
g/cm3
1 g/cm3

6. Calculating Density
Worked example:
Calculating density of aluminium:

7. Calculating Volume for irregular shapes
