We know that water is denser than air or a piece of paper is denser than rock.

How do we determine density?

Density is determined by measuring it’s mass and then dividing it by it’s volume.  

Let us take a solid cube of aluminium.

(i) The readings to be taken are the mass of aluminium and volume of aluminium.

(ii) Instruments used are :

  • digital weighing scale to measure mass
  • a measuring cylinder to measure volume which is filled with water
  • using pair of tongs we will put the aluminium cube in the water.

(iii) We will check the mass of the aluminium cube by simply putting it on the weighing machine. Now we will check the volume by putting that cube into the water. The initial level was x. The water level rises to y after putting the cube into it. To know the volume, we will simply subtract y-x. Hence, we know the volume.

To know the density, divide mass by volume. (Mass / volume)
