DENSITY OF A SMALL OBJECT
To measure the density of a small object e.g. ball bearing
1. Measure the volume by placing the object in a measuring cylinder. Take the volume before and after the ball bearing is placed in the water.
Volume of Ball Bearing:
- Mass of the ball bearing
Mass = _________________________________ kg
The density (ρ) = mass (kg)
NB: The mass of 1 cubic centimetre of water is 1 gram and
1 cubic metre = 1 000 000 cubic centimetres
- Density (ρ) = kg m-3
The density of the is kg m-3
Write a conclusion which states what the density of the object is and discuss why you think some objects are heavier than others.
