Density – Mass per unit volume.
p=m/v
How to find volume of irregular solids (displacement method):
- Measure the initial volume of liquid.
- Submerge the solid inside the liquid.
- Take the final reading of the liquid
- Find the difference in volume.
- Difference in volume = volume of solid.
How to find the density of liquids & solids:
- Find out the volume. For liquid, use a measuring cylinder. For solids, use the displacement method, or use the equation height * width * length
- Find out the mass, by using a beam balance or an electronic balance.
- Calculate density with the equation. p=m/v
Float or sink?
- A substance (solid or liquid) which is less dense than water will float.
