The Density Column

Using Density to Predict Position

If we put a solid into a liquid, and the solid is more dense than the liquid it will

If the liquid is more dense then the solid will

The same thing goes for all liquids. The least dense floats on top of more dense.

sink

Float

Question…

If the lead weight is dropped into the beaker of water… will it sink or float?

d= 11.4 g/mlWhat will happen if it is dropped into the mercury?

ALL solids have the same volume of 15.6 ml

Masses: Calculate the densities first!

pine = 5.4g acrylic = 17.3g steel = 128.5g

wax = 9.8g pvc = 13.7g

Draw the column with the densities
