Density

Formula

Mass = Density x Volume

Rectangular volume

Length x breth x height

Circular volume

PI x Radius2 x Height

Solid

molecules very close together

Vibrate

high density

Liquid

Intermediate closeness in molecules

Move in any direction

Medium density

Gas

Molecules are far apart

Move quickly in all directions

Low density

density of a liquid

1. Mass of empty cylinder

2. Liquid volume measured

3. Mass of liquid + cylinder measured

4. Subtract mass of the empty cylinder from full cylinder

5. D = M x V

Solid to liquid

Not a big change in volume

Liquid to gas

Space between molecules increases significantly

Gas to liquid

Volume decreases significantly

Measurement

Kilograms per meter2
