1. Density
Core
Describe an experiment to determine the density of a liquid and of a regularly shaped solid and make the necessary calculation
Supplement
Describe the determination of the density of an irregularly shaped solid by the method of
displacement, and make the necessary calculation

2. Density How to calculate the density of an object
You should learn:
How to calculate the density of an object
Examples of where density is measured in industry.

3. Summary Density = mass / volume Changing round the formula :
Volume = mass / density
Mass = volume × density
Density of water = 1000 kg/m³ = 1 g/cm³

4. To do
Carry out the experiments on the work sheet

5. Measuring density A solid 1. Find mass using a ………………...
2. Find volume by using a ………… ………….. to measure the change in the volume of water when solid is added.
3. Use the equation
A liquid
1.find mass of container using …………………
2.Measure volume of liquid using a ………
3.Measure the mass of the liquid and the container together
4.Subtract mass of container from mass of liquid and container to find the …... …. … ………
5.Use the equation
